What is Flea and Tick Medicine Poisoning?

The medication contains ingredients that can be harmful to cats, such as pyrethrins, pyrethroids and permethrins. Cats are more sensitive to these ingredients than dogs, but the poisoning is harmful to both types of pets.

The effects range from mild to severe, depending on the amount of exposure and condition of your cat. Flea and tick medicine poisoning can be fatal if it is not treated by a veterinarian.

Flea and tick medicine poisoning occurs when your cat has a negative reaction to the medication. The chemicals from the medication disrupt the nervous system and can lead to serious health problems. It is usually found in topical medication that is applied to the neck and back. The chemicals may also be found in medicated power and collars. 

Symptoms of Flea and Tick Medicine Poisoning in Cats

You may notice the symptoms of flea and tick medicine poisoning within the first six hours of exposure. Take your cat to the veterinarian if you notice any of the following symptoms:

  • Drooling
  • Vomiting
  • Diarrhea
  • Unrest
  • Tremors
  • Lethargy
  • Weakness
  • Incoordination
  • Hypothermia
  • Hyperthermia
  • Dyspnea (labored breathing)
  • Seizures

Causes of Flea and Tick Medicine Poisoning in Cats

There are several causes of flea and tick medicine poisoning in cats. The causes of this condition are as follow:

  • Sensitivity to the medicine
  • Medicine clinging to hair coats
  • Unusually low body temperature
  • Overdosing of medication
  • Ingestion of topical medication
  • Medication not being used as directed
  • Close contact to another pet being treated with medication

Diagnosis of Flea and Tick Medicine Poisoning in Cats

The best thing you can do for your cat in the case of poisoning is take them to the veterinarian immediately.

Your veterinarian will start by asking questions about their medical history and the symptoms they are displaying at home. You can also expect your veterinarian to ask about their exposure to the chemicals. It is important to answer these questions to the best of your knowledge. This will help your veterinarian determine the severity of the situation.

The next step is to give your cat a physical exam to check their current health and rule out other conditions. Expect your veterinarian to order blood work as part of the physical exam. Your veterinarian will use your answers, the cat’s symptoms, and the test results to make an accurate diagnosis.

It is vital to take your cat to the veterinarian as soon as you notice the symptoms of flea and tick medicine poisoning. Early detection and treatment can lead to a full recovery for your four-legged friend. 

Treatment of Flea and Tick Medicine Poisoning in Cats

Your veterinarian will treat the flea and tick medicine poisoning as soon as possible. There is a good chance your cat will need to be hospitalized during the treatment. This is done so your veterinarian can keep an eye on their symptoms and overall health. The good news is your cat may be released from the hospital in just two to three days.

Activated Charcoal

Your veterinarian will give your cat an activated charcoal to help them eliminate ingested chemicals from their body. The activated charcoal removes the chemicals before the condition becomes worse.

Bath With Detergent

Your cat may have been exposed to the chemicals when the medication was applied to their skin. In this case, your veterinarian will bathe your cat using a mild liquid dish soap.

Prescription Medication

Medication may be prescribed to keep the seizures and muscle tremors at bay. Your cat may also need to receive intravenous fluids during their hospital stay.

Constant Monitoring

The medical staff will monitor your cat for several days to ensure they are recovering from the poisoning. This includes monitoring their blood glucose, body temperature, and kidney function. Your cat may need to remain hospitalized until their symptoms fade and their body is functioning normally.

Recovery of Flea and Tick Medicine Poisoning in Cats

Your cat will be released from the hospital once they have recovered from the flea and tick medicine poisoning. However, the road to recovery does not end when your cat is released from the hospital. It is important to schedule a follow-up appointment so your veterinarian can make sure your cat has recovered from the poisoning and treatment.

You can prevent flea and tick medicine poisoning from happening again by using the medication as directed. You should never use medication on your cat that is designed for another animal. It is important to contact your veterinarian before using flea and tick medicine on your cat. 

Taking your cat to the veterinarian as soon as you notice the symptoms can lead to a full recovery. Unfortunately, neurological complications or leaving this condition untreated can be fatal for your cat.

Has Symptoms

breathing

So I have two cats, Mia and Luna an 8 month old and a 5 year old. I applied the sentry flea medication wrong to where they are able to reach it and lick it off. Once we realized they had gotten it in their mouth the panic had set in and we rushed and grabbed a soapy rag and scrubbed the fur around the area and then rinsed and dried as much as possible. They seem normal enough but a little off. I've checked for salivating, weakness everything honestly. I haven't left their side. And no symptoms. The older one has started breathing heavy here and there but not dangerously heavy. We've been feeding them salmon, milk, water and food. Still have appetite and still running around a little. They seem a little uncomfortable though.

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
You should continue to keep an eye on them for another few days, there is no treatment for ingestion of flea & tick medicine apart from rinsing out their mouths and bathing the application site. However, if symptoms start to develop of salivation, twitching, shaking or anything else concerning you should visit your Veterinarian. Regards Dr Callum Turner DVM

Weakness

Falling Over
lack of appetite
Vomiting

We have four cats. Out oldest (3 years) was given 'Adam's Flea and Tick Spot On' In November. It was the correct choice for his weight and he was fine for an hour, but then he started to wobble around and his eyes were darting and erratic. We have him a bath right after we saw him acting weird and he seemed to get better a few days later. He still wobbled and he seemed to have some weakness on his left side. Now his head is tilted and he constantly falls over. He mews constantly and he becomes irritated very easily. We try to keep him away from the other cats because he's previously attacked any of them that got near him. He's become very unbalanced and he can't jump up that great anymore. He'll fall right down and he has hurt himself in doing so. A few days ago he had a seizure like episode and he exhibited even more weakness on his left side. His head is permanently tilted to the left as well. It's hard for him to keep any food down and he won't drink water unless we hold him in front of his water bowl. Could it be caused by the flea and tick medicine that we gave him back in November? And if so, why has it not left his system?

Michele King

Thank you for your email. The medication in the Adam's product may have caused neurologic insult that isn't resolving for Nightmare, or he may have unrelated neurologic disease occurring. He might benefit from treatment for his seizures and signs. It would be best to have him seen by a veterinarian, as they can examine him, evaluate his neurologic system, and determine whether treatment will help. I hope that he recovers okay.

Has Symptoms

Vomiting
Lethargy
Paw flicking

I gave my two cats, Mina (3 yo) and Lucy (1.5 yo), flea medicine a couple of days ago and I have noticed Mina being lethargic and she also vomited once. Mina has reacted this way to flea medicine in the past but I never thought much of it other than a bit of an adverse reaction. She usually gets over it in a couple of days, though. Lucy has been more normal, but has been flicking her paw, which I didn't know was a symptom of poisoning until I looked it up. After looking into it and realizing that this is more serious than I thought, I'm worried. Do you think they'll be okay? I'd rather not have to take them to the vet if it's something that they'll get over in a day or two.

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
Subtle symptoms like paw flicking are concerning but not emergencies if your cats are still eating/drinking/defecating/urinating; if there are other symptoms like ataxia, seizures or other concerning symptoms you should visit your Veterinarian immediately. Keep a close eye on both cats and if the symptoms progress you should visit your Veterinarian or an Emergency Veterinarian; also call the helpline on the product package to ask about product specific advice (many different products with different ingredients).

Has Symptoms

Eye Redness

Lethargy
Dehydration
Strange Behavior

One of my 9 month old kittens had an adverse reaction to Advantage II flea and tick topical medication. His symptoms were primarily lethargy, dehydration (most notable in his eyes as the irises paled in color, pupils constricted, third eyelid did not retract), and isolation (stayed in the closet for two days straight). After three days of observation, food, and hydration with flavored water he did make a full recovery.

Now that a month has passed it's time to apply the medication again, but I don't know if I can give him a different brand, like Frontline. Is it likely that he'll have a similar reaction to other brands of medication? Is it too risky, and are there any other options so that he can be just as protected as his sister?

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
If you have concerns about Charlie, it would be best to use a different product like Frontline (fipronil) which uses a different active ingredient than Advantage II and see how he gets on. Ensure you are using a flea control product intended for cats and the dose is appropriate for his weight. Regards Dr Callum Turner DVM

Paw flicking

Fipronil -

I applied Fipronil on Jan 15, and seizures started the next morning. (I live in rural Africa and there arent any veterinarians) She has another seizure that evening and I started her on 1/4 tablet of 5mg diazepam in the morning and evening to control seizures while the medication worked it’s way out of her system. I kept her on the diazepam for three days and then weaned her off. Yesterday was her first day with out the diazepam, and there’s have been no further seizures after the first two on the 16th. I also bathed her.

She continues to have muscle tremors, a lack of appetite, and is dehydrated. I have been giving her 50ml of water and 10 ml of WHO ORS solution per day for the last two days via a syringe (she probably weighs just under a kilo). She has had 6 bowel movements since the onset of symptoms. Today is day 6 and she still feels terrible. She is listless, has moderate muscle tremors, and shows little interest in drinking on her own.

I am planning on continuing to administer fluids hourly and trying to get her to eat kitty treats, but I am really worried that she is still experiencing symptoms nearly a week after the poisoning event. She is very likely inbred (that’s a problem with all animals here in the village) and I am wondering if that might be a part of the issue. My current strategy is to get as much throughout (food and water) through her as possible to try and flush her system. Please advise; much appreciated.

Thank you for your email. You are doing everything that you can to help Piglet, from your email. Treatment for toxicity to flea and tick products involves bathing to decontaminate, intravenous fluids for supportive care, and controlling seizures and tremors until they resolve. Without access to IV fluids, you are doing the best that you can do by giving her small frequent amounts of food and water to keep her hydrated. It can take 1-2 week for her to start to eat on her own if she was severely affected by the medication, and supportive care is what she needs in the meantime. I hope that she recovers, and think that you have done a good job helping her so far with limited access to veterinary care.

My 8 year old cat had a bit of a cough and sneeze, took him to the vet. His temp was normal and breathing was regular. I was given oral antibiotics in case of a respatory problem. While there they administered a flea and worm treatment to the back of his neck.10 hours later he is vomiting, drooling, lethargic and breathing with his mouth open. Is this a reaction to the flea treatment?! Did my vets tech not administer it properly?!

Thank you for your email. That does not sound like a normal reaction to topical flea prevention, or antibiotics - It would be best to take him back immediately and have him assessed and treated as needed. He may be having an abnormal reaction to the medication, or it may be unrelated. He does need to be seen immediately if he is breathing with his mouth open. I hope that he is okay.

I was clicking to fast his eyes are not red or bulging, they are watery

Paw flicking only

I used bio spot active flea treatment for my cat 1 1/2 possibly 2 years one does as directed at 330 4pm eastern time I came home around 9 pm and noticed her flicking her leg like she got it we or stepped in something. And it was becoming a continuous reaction every time she got up to walk. Slam researching to flea and tick reactions into Google and I see paw flicking and licking of toes is a reaction. Which I saw the back toe licking occur as well. Thus I immediately washed her and the spot of application. However this is the only symptom that has been showing everything else she acts normal plays eats and acts like herself. Just when she gets up to walk she flicks her paws back left or one of her front paws. But nothing else is showing as symptoms wise. And nothing matches the symptoms that would warrant a immediate vet appointment. Or hospital stay. And I did see that the flicking was stated to be temporary and will go away 72 hours from when it started. Is there a way to detox her home remedy style to aid recovery of side effect. While watching for progressive symptomatic development that would be like ok now we gotta take her in she now has multiple symptoms.

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
When symptoms like paw flicking present after the administration of a flea and tick spot on medication, washing off any residue is always best but normally after five or six hours (even thirty minutes to an hour) the medication would have absorbed and would be dry. In these cases it is a case of waiting for the symptom(s) to decrease in severity and disappear; whilst you may have read 72 hours it may take longer (week or more). If any other symptoms present or the current symptoms increase in severity you should visit your Veterinarian. Regards Dr Callum Turner DVM

Tremors
Shaking

Medication Used

PetLock

I have multiple cats who are having tremors and are shaking after receiving their flea treatment. My mother applied to them flea control for dogs (I believe it was the PetLock brand) even though it said do not apply to cats on the box. She said it would be fine as long as she measured the weight and gave them amounts according to that weight. I wanted to believe it would be fine but now some of our kitties are having negative reactions and i'm very scared and I don't know what to do. I'm worried it will only get worse but so far its just been the shaking and it's not happening to all the kitties we have. Some of the shaking isn't as severe and some is to the point where the kitty lays there and can't really move. However, to those who have been shaking, they seem to still be up and moving around and acting relatively normal. The flea medication was applied yesterday in the afternoon and we started seeing the tremors on multiple cats by evening. They still seem to be eating and drinking though. I'm worried it will get worse though and I don't know what to do. The cats affected are 1-4 years.

Michele King
Dr. Michele King, DVM

Thank you for your email. Dog flea medications can be highly toxic to cats - that is why the warning on the box says do not apply to cats. It would be best if they were seen at your nearest emergency clinic, as they will be able to treat them for the toxicity. The toxin in dog flea control can cause tremors, seizures, and possibly death. If you aren't able to get them to a veterinarian, you need to wash any residual flea medication from them, but since it has been over 24 hours, they may have absorbed the majority of the medication. They may need IV fluids or supportive care. I hope that they are all okay.

HI. I gave my cat flea medication last night and he began hypersalivating 10 minutes later. I washed the flea medication off and he was fine through the entire night. This morning when I gave him food he ate it and then threw up a little bit of that. Do you know if something is wrong?

Callum Turner
Dr. Callum Turner, DVM

Sometimes after giving a cat (or dog) a topical spot on flea treatment, they may be able to lick it and end up salivating or having other symptoms; in these cases it is a case of waiting it out if there are any symptoms present. You should ensure that Rillo is hydrated and offer small bites of boiled chicken to tempt appetite. If you don’t see any improvement or the symptoms get worse you should visit your Veterinarian.

anxiety

My cat Lagertha never had anxiety until about 6 weeks ago when i treated her for fleas with Advocate neck drops. It took her a week or so to come near me again, and several weeks for her anxiety to calm down. it took a couple of weeks before she would sleep on the bed again, but not near me as she previously did. Although she no longer runs away from me, i think she has developed a bit of a fight or flight (mainly flight) response that i would like to try and get her past. Prior to this treatment she was a very affectionate cat that was not scared by anything. Now she reacts badly to sudden noises, or movements. i truly do believe it was triggered by the application of the flea medicine. Last night i gave her 'adopted' brother Ragnar the same medication as he hadn't reacted badly to their first dose. She became extremely anxious the moment she smelled the product, and wouldn't eat. She usually eats anything and whenever she can. She has settled overnight, but her anxiety has become worse, but not as bad as before. i really just would like to get her anxiety free as she was never susceptible to anxiety. i have raised her since i found her at 5 weeks old so i know she was never anxious prior to this.

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
In these cases I recommend moving over to a different brand of flea & tick control since there are many good products on the market; sometimes some cats may have an adverse reaction to a product which can cause a variety of symptoms, there is no direct treatment for anxiety and it is really a case of waiting it out since the issue now after six weeks is more behavioural than medical in origin. Reassurance, love and care is best; there is nothing medical I can recommend for you at this time. Regards Dr Callum Turner DVM

Thanks for the advice. We tried an oral brand. She freaked out when she smelt the chemical smell of the tablet, but after administration (which was nearly impossible as she was so scared) she was fine. Her anxiety is back to as 'good as it gets' and hopefully she will continue to improve with time.

Thanks!

A cat licking spot on flea treatment products from a dog is serious since the products used on cats and dogs are different in composition not just strength and are dangerous for cats; I wouldn’t wait for a few days but visit a Veterinarian immediately or call the manufacturer of the product on their customer care line, each product has different active ingredients so treatment would be dependent on the product.

Gave my cat advantage last night and I applied it wrong so she ended up licking some of it. This morning I noticed she isn't eating or drinking and keeps making funny faces like she still has the taste in her mouth - sort of gagging. she just now ate a bit, but she still isn't drinking.

Michele King
Dr. Michele King, DVM
461 Recommendations
Shenan, thanks for contacting us about Rodriguez. As long as the Advantage that you applied was specifically for cats, if she did lick any of it, it isn't toxic, it just tastes really bad! You can try giving her some soft food, heat it up a little bit in the microwave so that it smells delicious to her, or some tuna fish or something that she will really like. Once she gets the taste out of her mouth, smells delicious food and starts eating again, she should be okay. Canned food has a lot of water in it, so if she will eat the canned food until she starts eating her regular food again, she will get enough water for the short term. If she still isn't interested in eating after that, you might need to take her to her veterinarian for some anti-nausea medication or appetite stimulants, but she should start eating normally fairly quickly. You don't want her going more than a couple of days without eating, so hopefully she returns to normal fairly quickly.

In cases of flea and tick medicine poisoning, it is just a case of offering supportive and symptomatic care whilst everything gets out of Apollo’s system; you should encourage eating and drinking by trying different wet foods (mix with a little water for hydration) and slightly warm up the food to make it more appetising.

Thank you for your question. Unfortunately, without more information and without examining Storm, I'm afraid that I can't be of much more help to you - That would be a very unusual side effect from Advantage, even at a higher dosage than she should have gotten. Some causes for hing end paralysis include trauma, degenerative nerve disease, meningitis, or tick paralysis. It seems that your veterinarian has recommended an MRI - if that is not in your budget, perhaps a second opinion at another veterinarian might help - sometimes having more people looking at her and thinking about what might be happening with her helps. I hope that she recovers.

Thank you for contacting us about Stormy. Without examining him, I can't comment on whether the lump is serious or nothing to worry about, unfortunately. In a 10 year old cat, it could be an abcess, a benign growth, or a tumor that needs to be removed. It is unlikely that it is related to the topical flea treatment. It would be best if he were seen by his veterinarian to figure out what the lump is and how to treat it.

Wobbly

We bathed our cat (3 years old and about 5-6 pounds) and then sprayed her with the Adams Flea and Tick Spray. She stayed in the bathroom after treatment and i went to check on her about 30 min later and she had trouble with balance and some weakness. She also seemed to be slightly confused. I went and rinsed and dried her off and kept her warm. She started to act better and purring. I set an alarm to wake up and check on her and she still was stumbling some. I took her and gave her some food and she ate very well and drank some too. She also used the litter box and there was no diarrhea. I stayed up with her all night and she could now walk while on the floor without any real problems and can almost jump up on the couch. However, she still loses her balance some as she is scratching. I assume it is flea treatment poisoning since this happened after the treatment. Is she going to be OK?

Thank you for contacting us about Mittens. It does sound like she had a reaction to the flea treatment, yes. Washing it off of her body was the perfect thing to do. If she continues to improve, continues to eat and drink normally and gradually regains her balance over the next 24 hours, she will probably be fine. If she stops eating, seems lethargic, is vomiting or having diarrhea, or isn't regaining her balance, she should be seen by your veterinarian. For future flea treatments, it might be better to use one of the more trusted prescription forms that are available from your vet. I hope that she recovers normally!

Spitting up

I took in a stray cat not fully grown I'm guessing around 6 months and put a flea treatment on her and she wouldn't stop licking it. It's been about 2 days and she's kinda foamy around mouth and spitting up clear foamy liquid!! I'm very concerned. What should I do??

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
Any flea and tick treatment should be given at the back of the neck where a cat is unable to lick the area; also you need to make sure that you apply a cat flea and tick product and not one that is intended for dogs. If Cleo is foaming at the mouth, you should rinse her mouth out thoroughly and ensure that she is hydrated and eating; there is no at home treatment and most of the time it is a case of waiting it out. You should visit your Veterinarian for a once over and for symptomatic care. Regards Dr Callum Turner DVM

Hi, my cat is having a reaction to advantage flea treatment. She has been lethargic (hiding and laying in the closet) for over 48 hours, but will still walk around if bothered. She isn't eating or drinking, but I got about 1.5tbs of water down her this morning. She had a fever but after I gave e her water she cooled off. I also noticed that her urine was dark this morning.

Should I bring her to the vet this morning? Or should I keep her at home and give her water myself.

Dustin, thank you for contacting us about Navi. I'm sorry that she is having this problem It would be best to take her to your veterinarian this morning for an exam, and possibly IV fluids and supportive care until she is able to eat and drink on her own. She is probably very dehydrated at this point, and there is a risk that she will start to have organ failure if her hydration and blood pressure aren't maintained. If your veterinarian checks her out and decides that she is safe to recover at home, then you can manage her there, but it would be best to make sure that she is okay before making that decision.

i put flea and tick topical treatment on my cat 3 1/2 weeks ago and he's been having seizures almost one a day, whatv i would like to know is will the seizures go away once the medicine is out of his system?

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
If the seizures are related to the application of a flea and tick medication, they may resolve after a month or so but may persist in some cases; you should contact the manufacturer of the product to advise them of the seizures and they may have some product specific advice for you. If you haven’t already, visit your Veterinarian for an examination as they may be able to give you something to manage the seizures in the short term. Regards Dr Callum Turner DVM

Also, I have no money at this time to take him to a vet, and hope that you can let me know if the seizures will go away. I already bathed him in dawn a week after seizures started, i didn't think of bathing him right away because i didn't realize the seizures could be caused by the flea treatment til i called the emergency number on the box of Sergeants. He went 2 days without a seizure a couple days ago, so hoping that is an improvement? thank you

I used a topical Sentry PurrScriptions Plus flea treatment made for cats 5Lbs and over. My cat is 7 Lbs. I applied it at 5pm and the next morning at 7am (14 hours later) I noticed my cat would all of a sudden run 5 feet and stop, looking confused. Visibly she did not look like anything was wrong but when I pick her up I can feel a slight shaking in her body. I gave her a bath with a very mild dish soap that the Vet had recommended for cleaning my other cat. She is drinking, going to the bathroom, and moving about normally but the slight shaking and the weird burst of energy has me concerned.

Callum Turner
Dr. Callum Turner, DVM

In these cases it is really a case of waiting out the effects of the spray, I would contact the manufacturer to discuss the symptoms and they may have some product specific information to tell you and may also log it for pharmacovigilance. Keep an eye on Monkey for the time being and ensure that she is hydrated but she may require symptomatic care from your Veterinarian if symptoms get worse. Regards Dr Callum Turner DVM

Twitching, tremors

I put dog flea treatment on my cat about 4 hours ago, I had realized after 30 or 40 minutes after it was on that she had it smeared off her neck and was trying to lick it, so I bathed her and washed it off of her the best I could. But almost 2 hours ago she started twitching and acting really weird, so I called poison control and wasted money speaking with them because they told me they was only able to tell me to take her to the vet. I only had $90 on my card, to take her to the vet hospital I'd have to pay $200 just for the visit, not to mention whatever the amount is for her treatment and medications, but I spent $65 of my 90 just to call the poison control. So I absolutely don't have money to get her to the vet now and I have no clue what I should do for her, she is twitching and having tremors, occasionally trying to walk but she doesn't make it far. What can I do for her?

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
You should never put dog flea treatment on a cat as their internal physiology is different and cats do not tolerate the medication whether she would have licked it or not you would still see these symptoms; there is generally a warning on some brands which specifically say don’t apply to cats. As for treatment, control of any seizures with medication is the main one if seizures start to occur; otherwise you need to keep Baloo hydrated with water (mix in some unflavoured Pedialyte) and give some small portions of smooth cat food from your finger for her to lick off. Ideally you should visit a Veterinarian, try to find a charity clinic in your area just for a once over. Regards Dr Callum Turner DVM

I use Simple Guard 3 for my dog (60lb pit mix) and sequester my cats after application. Usually, my cats are elsewhere when I apply it, but unknown to me until after application in the kitchen, my cat was in the next room. I applied the medicine to my dog and let her go, and she walked into the next room and shook herself. I think a small drop of the medicine got on my cat, but am not sure. There was a small wet spot on his back, but I wasn't sure if it was a recent grooming or a splash got on his coat. Since I didn't know, I washed his coat with soap and water shortly after I saw the wet spot, and called my ER vet. They told me that unless he shows symptoms all they could do is give him another bath. They were vague on how concerned I should be, but I am wondering how toxic is this stuff if only a small drop got on him and was washed off shortly after? I'm nervous because of the large warning on the back of the box about fatality to cats.

Callum Turner
Dr. Callum Turner, DVM
1953 Recommendations
You would be surprised by the number of people who don’t read those warnings. However, if there was a small drop on the fur which was washed off quickly and Peyton didn’t lick it, then there is little to be concerned about apart from looking out for symptoms of poisoning which are listed on this page. There is no direct treatment for this type of exposure and any treatment given would be purely supportive and symptomatic. Regards Dr Callum Turner DVM

I used Revolution, meant for five pound cats, on my four-and-a-half pound kitten. I thought he was close enough to 5lbs that it was okay. Well, we washed it off thoroughly with Dawn about 12 hours later when we noticed he was shivering and lethargic, but he is still shivering and lethargic. Any vet open this week, with the surrounding holiday, will be very expensive and we don't have a ton of money as we just had to pay for some big automobile repairs. Am I going to lose my kitten? We applied Revolution three days ago and he's still trembling a little and lethargic.

He is eating, drinking, and using the litter box. He just isn't moving much for anything else. Is he going to make it? I'm so worried.

I used Natural Chemistry Flea Shampoo for cats of all ages on my cat, but I was not able to rinse as thoroughly as I would have liked to, due to the fact that she hates water. I had to move her to a different house for a few hours while I treated the rest of the house for fleas. During this time, she frothed at the mouth briefly, but it appeared that it was a result of licking the shampoo and the moisture causing it to foam up. She's home now and very calm, very exhausted from the stressful day she's had, and a little nauseous. I'm concerned about what I should watch for in the coming days to make sure she's doing okay.

Callum Turner
Dr. Callum Turner, DVM

It is important to ensure that you thoroughly rinse any shampoo product used on your cat (I understand that they don’t like water); the foaming at the mouth most likely was due the shampoo still being present but I would urge you to thoroughly rinse Charlie again to remove as much as possible. Look out for neurological signs and vomiting; make sure that Charlie is drinking but otherwise alright. Regards Dr Callum Turner DVM

I have given my Cat "Lowkii" Hartz Ultra Guard One Spot Drops. once a month flea treatment. Keeping in mind that I have lost a cat to the same type of meds, (I certainly never meant for it to happen), Have to ask though, How long before I should see any adverse effects if it is going to take place at all. I am aiming for it not to happen, and because my other previously died, I want to be pro active in seeing that he gets medical attention as spoon as I can to ensure that he will be okay. I can't go through that again. especially seeing it and feeling helpless the last time. It was a traumatic event that will forever be with me. I feel so guilty and so much pain and sadness for that you can;t even imagine. So again, how long should it take if it will show up at all.

Callum Turner

Symptoms usually present themselves within a few hours (less than ten); normally lethargy and loss of appetite are the most common symptoms but others may include vomiting, diarrhoea, tremors, seizures among other symptoms especially if Lowkii was able to lick the application site area.

Wobbling

Hi i de flead both my cats 3 days ago now but didnt realise that the drops where actually for my 40kg labrador and covered fleas and worming and holli my 2nd cat showed symptoms the next day and her symptoms where that she was a bit unsteady when jumping up onto things but could walk fine although a little bit slow. Today she looks a little better with her jumping up but is still slightly wobbly. She has also gained a right watery eye which is clear fluid just like tears are.

My 1st cat sylvester didnt show any symptoms before yesterday then i noticed that he wasnt himself at all as he couldnt even walk straight and his back legs/feet were sometimes crossing over one another and he had to lean up against almost anything that was in his path way before trying to walk to where he wanted to go and then leaning up against the next thing he could until he got to the room he wanted to be in.

He also usually stays out all day and then comes home late in the evening then will go back out again about 6-7am and then wont be seen till the evening but yesterday he was asleep on my bed all day and didnt even move. Both cats are still eating and drinking but sylvester decided to go out this evening about 6 ish and i am really worried that anything could happen to him if he cant move his feet properly or walk in s straight line 😢 i just cant believe i used the dogs one on my 2 cats and thats a pipelet each for dogs upto 40kg, i feel so dumb and so awful. Im guessing it could happen to anyone who has multiple pets as i have 3 cats in total and a dog but luckily i wasnt able to flea my other cat tinkabell as she was out at the time.

Update: sylvester has just come in and jumped up on my bed all soaking wet from the rain and was meowing for his food. I am SO SO HAPPY AND RELIEVED THAT HE IS NOW HOME AND SAFE. I have just watched him walk and it seems as tho his feet movements are functioning correctly altho he is still walking a bit slower than usual, but didnt have any problems with jumping up onto my bed.
I am in recipt of state benefits so am really inable to pay a large vet bill for my two cats 😢😢

There is a lot of these types of cases (as seen in the newspaper links below) and the use of dog flea products containing permethrin on cats may result in death; you should contact the manufacturer of the product to ask about the ingredients of their products and the toxicity in cats and try to contact a charity clinic or nonprofit in your area to check Sylvester and Holli over to be on the safe side. Tinkerbell may be still at risk if she licked any of the product or some of it rubbed on her from bedding etc… Regards Dr Callum Turner DVM www.express.co.uk/life-style/life/493673/How-to-get-rid-of-cat-fleas-safely www.dailymail.co.uk/news/article-492519/Hundreds-cats-killed-flea-treatment-dogs.html

I recently just has an accident with applying Dog medication on our cat.. We ran to the ER as soon as possible once we noticed the mistake and he started having tremors. He is out and back home now, we however have been giving him a oral medication to ease the tremors when they occur and can give them every 8 to 12 hrs as needed. (Sorry can not remember the name of the medication at this time, but its a 500mg tablet. We give half of it every 8-12.) Today will be his third day since coming home and he is still experiencing body tremors when the pill wears off. So my overall question is, does anyone know how long we can expect him to experience these reactions? I feel terrible this happened to him and I just want to know when we can expect him to be "Normal" again.

Generally these tremors will continue to occur whilst the medication is still in his system; flea and tick medications generally offer protection for a month so this is the type of timeframe you are looking at. There is no treatment apart from symptomatic and supportive care which you are currently giving; you pretty much need to wait it out. Regards Dr Callum Turner DVM

I just put the Hartz Ultra Guard Pro treatment on my cat. I used it as it said but his fur is so thick that it didn’t all stay on the back of his neck where I put it. Well he started to lick the spot with the treatment that had fallen down. I did wash off that extra bit so he couldn’t lick it any more. He didn’t ingest a lot of it but he has been acting lethargic, he has had a little water but hasn’t really eaten much. He also had a really runny poop earlier that was super stinky!

Keep a close eye on Mo, it was good that you cleaned the excess off so he couldn’t get all of it; but the amount consumed by mouth would cause lethargy.

It is possible for a cat to be allergic to more than one flea treatment product. Other products like Frontline are usually tolerated better than Advantage or Revolution although may be less effective.

My cat is indoor/outdoor and I think she might have this type of poisoning however I wasn't able to get her before she took off and typically she stays around the house and comes when I call her. But since she hasn't my question is, what happens if it goes untreated? is it something she could recover from? I assume it would take a longer period of time if so.

My 2 cats have been acting strange since switching to Frontline. They are both acting paranoid, twitching, running like something is chasing them and hiding a lot. Not normal at all. The symptoms of Hyperesthesia look very much like their symptoms. Is this a rare side effect of Frontline poisoning?

why would fleas die without treatment
