What are Allergic Reaction to Vaccines?

A vaccine is the modified form of an organism, containing the antigens for a disease, but are not infectious. When the agent is injected, the immune system responds by creating specialized antibodies for that specific infectious organism. The purpose of the vaccine is to stimulate the immune response to make specific cells to keep circulating the body. Therefore, when the feline is exposed to the virus or bacteria, the immune system is prepared to fight it. Sometimes the immune system overreacts, causing an allergic reaction to vaccines in the feline. Symptoms of an allergic reaction can be mild, moderate or severe, and vary depending on the type of vaccination received. 

It is normal for a cat to experience a few mild side effects after receiving her vaccines, such as local swelling or pain at the injection site, but if hives appear, your cat could have an allergic reaction to a vaccine. Your cat’s immune system plays a vital role in protecting the body from infectious ailments to keep her healthy. Making antibodies against parasites, microbes, bacteria and viruses is one of the most important functions of the immune system. Unfortunately, this complex system cannot make specialized cells to fight every disease that invades the body, so vaccines are given to help the immune system prepare. 

Symptoms of Allergic Reaction to Vaccines in Cats

An allergic reaction to vaccines in cats can be mild, moderate or severe and can appear within a few hours to several days after the vaccination was given. Severe reactions are usually associated with killed varieties of vaccines such as feline leukemia virus and rabies. 

Mild Vaccine Reaction

  • Fever
  • Loss of appetite 
  • Swelling, redness or pain at the injection site
  • Temporary lameness 
  • Temporary joint soreness 
  • Sneezing lasting roughly 4-7 days
  • Low activity levels 

Moderate Vaccine Reaction 

  • Urticaria (hives) 
  • Pruritus (itchy skin)
  • Swelling of the neck, eyes and/or lips
  • Redness 
  • Fever

Severe Vaccine Reaction: 

  • Very sudden allergic reaction (less than 24 hours) 
  • Breathing difficulties 
  • Diarrhea
  • Vomiting 
  • Decreased blood pressure 
  • Pale mucous membranes
  • Cold extremities 
  • Cardiac arrest 
  • Shock 
  • Seizures
  • Collapse 
  • Death 

Causes of Allergic Reaction to Vaccines in Cats

An allergic reaction to vaccines in cats is caused by an over-reactive response to the immune system. The antigen within the vaccine is used to stimulate the cat’s immune system to create specialized antibodies against the virus, bacteria or disease. However, the nature of some feline immune systems are hypersensitive and overreact to the introduced antigen. Common feline vaccinations that have been known to cause an allergic reaction in cats include vaccines against: 

  • Feline Panleukopenia
  • Giardiasis
  • Bordetellosis
  • Feline Immunodeficiency Virus
  • Feline Infectious Peritonitis
  • Chlamydiosis
  • Feline Leukemia Virus
  • Rabies
  • Feline Herpesvirus and Feline Calicivirus

Diagnosis of Allergic Reaction to Vaccines in Cats

Allergic reactions can be caused by a variety of elements in your cat’s environment, causing similar symptoms of a vaccine allergic reaction. Therefore, the veterinarian may want to perform a differential diagnostic exam such as an intradermal allergy test to rule out other causes. 

To diagnose an allergic response to vaccines specifically, the veterinarian will review your feline’s current vaccination history, paying close attention to which vaccines were scheduled to be administered. The vaccination history will reveal which vaccines were administered, the date of administration, and location. The doctor can then pair the medical record with your cat’s current condition to diagnose the allergic reaction to a vaccine. 

Treatment of Allergic Reaction to Vaccines in Cats

Mild to moderate cases of an allergic reaction can be symptomatically treated with anti-inflammatory drugs such as a corticosteroid. A feline with a mild or moderate allergic reaction to vaccines should return to normal health within a week. However, moderate allergic reactions can worsen over time and become severe, so the feline will need to be monitored for the duration of the allergic response. 

Cats with a severe allergic reaction to vaccines need to be rushed to the veterinary emergency clinic right away. The doctor will begin administering life support to the feline including intravenous fluids and oxygen. The feline’s airways will be monitored to ensure they do not close at any time. Felines that are stabilized will likely survive anaphylaxis, but will require hospitalization for a couple days after anaphylaxis shock before returning home.

Recovery of Allergic Reaction to Vaccines in Cats

Allergic reaction to vaccines in cats is very rare, but if your feline has a history of vaccine hypersensitivity talk to your veterinarian. The next time the vaccine is needed, the veterinarian may include an antihistamine to prevent an adverse reaction or eliminate the vaccine from your cat’s vaccination schedule altogether. It is important to discuss vaccinations with your veterinarian to fully understand the risks and benefits that come from vaccines. In most cases, the benefits of vaccinating your cat outweigh the risks, which are small by comparison.

Lump :(

Hi, I’m following up on my previous question re: my cats vaccine lump. It is 12 days and it is a lump now not fluid really.

I have read online recently that it isn’t a good idea to vaccinate while under or straight after anaesthetic which has made me more worried now abt the lump. I asked the vet on the day would it be too much for her and he said no. I’m never going back! I have also just read that 1 dose of FVRCP will usually last a cats lifetime and shouldn’t be given more than once or twice so I’m ok with that for now. If I can get her through this lump. It is 12 days now.
So do you think my cats system was already too compromised after anaesthetic to have the nobivac trio. As they didn’t even give me a card and I had to phone to find out what she had. The receptionist had no idea and the vets where in meetings. I got the nobivac trio out of her but I’m hoping it was without the addional FeLV shot. I read that after anaesthetic her immune response to the vaccines would not have been at full capacity and can also lead to vaccine failure. I should have taken her back instead of this but she’s so tightened of the vets and because he agreed it would be fine, I went ahead. Btw.... she had dental cleaning with 0 extractions.
I’m dealing with a lump now and I’m so sad. She’s completely oblivious.

Thank you so much for the free advice.

It is quite common to vaccinate at the time of an anesthetic, and most cats handle the vaccination very well. Since you are so worried about Tizer, it really would be a good idea to have a recheck for her. Your veterinarian can test that lump and clear your mind as to whether you have anything to worry about or whether she is having a mild reaction. I hope that all goes well.

She was fine after, playing eating and meowing, now she is completely in active and seems to have a hard time breathing.

There are many possible side effects with the rabies vaccination (fever, swelling, loss of appetite, lethargy etc…) but it is still a better option than a cat being exposed and unvaccinated; if Kyoto is having breathing difficulties I would recommend visiting your Veterinarian or an Emergency Veterinarian as I cannot determine how bad the breathing difficulty is.

Our 4y/o female cat is petite,weighing just 6 # and active. Last fall she received her FVRC and leukemia shot and was lethargic for 29 days. We informed our vet who minimized our concerns since she was eating and drinking. This year, we asked for the shots to be separated between 2 different dates a month apart. She handled the FVRC very well...came home and was her usual nutty self. However, she is experiencing lethargy after the leukemia shot given 2 days ago. We understand the importance of the leukemia shot but worry about It's affect on her.

Strange Behavior

My kitty, who was a stray before we took her in, was vaccinated yesterday. FelV, FVRCP, and RV. She was fine yesterday but isn't feeling well today. I know vaccines can make kitties a little lethargic, but she also seems to be very skiddish and afraid of normal things like shoes, her litter box, or anything that's on the floor. She meows loudly when I pick her up and I hope that's just soreness from the injection site. She is also favoring her front paw this morning but I don't know what she could've done to injure it overnight. She's sleeping under a couch in our basement which is very odd for her. She does eat her crunchy treats but is just acting odd.

Kit might be a little sore from her vaccines yesterday, and that will sometimes last for 24 hours. If she continues to act strangely tomorrow, it might be a good idea to have her re-examined to make sure that she is okay.

My 11 week old kitten just got his first set of shots and now the bridge of his nose is swollen and a tiny bit of pink blood just came out. Is this a reaction to the vaccine? He did have severe conjunctivitis a few weeks ago but it’s better now and he’s also eating normally and drinking.

If the swelling happened right after the vaccine, it is possible that it is related, yes. The bit of blood is unusual, though. If his swelling doesn't improve over an hour or so, or if it seems to be getting worse, it would be a good idea to take him have to your veterinarian to have him looked and see what is going on and if he needs any treatment.

Cats can get swellings at the point of injection that resolve in a week or two, but they can also get infections and tumors from injections. It might be best to have Nico rechecked just to make sure that there isn't any problem with the site, since any discharge is unusual with a mild reaction.

Hi Kirti. I'm sorry that your kitten is having these problems. Unfortunately, without knowing what medications were given, I'm not sure what the cause of her being restless might be. It may be her fever, or her diarrhea, or a side effect of the medication. It would be more helpful for you, I think, to call her veterinarian and ask if that is a side effect of any of the medications, or if you should be more concerned. I hope that all goes well with her.

It is not unusual for cats to have a reaction or side effects to the administration of vaccines, however the side effects caused by the vaccines are much better than a cat contracting a fatal infectious disease. Keep an eye on Harley for the time being, these effects may last a few days; prevent her from licking herself and ensure that she is hydrated and is eating. If you have any concerns, return to your Veterinarian. Regards Dr Callum Turner DVM

Dr. Michele King, DVM
1604 Recommendations
A week is a long time to have a reaction to a vaccination, but kittens are prone to having problems with viral diseases if they have a stress, and the vaccine may have stressed her immune system. If she seems to be having more difficulty, it would be a good idea to have a recheck for her, and see if she needs any treatment. In the meantime, keeping her in a humidified environment might help, such as running a hot shower for 10 minutes and keeping her in the steamy bathroom.

Fluid/ Swelling

Hello, I took my cat to get her first injections when she was about 4 and never went back for the 2nd shot (3 weeks after) this was mostly because she was an indoor cat, didn't have access to the outside at all or other cats. Shes 10 now and has been to the vets 10 days ago for a dental cleaning, as I have now moved house and she likes to go in the garden; I thought she should start her injection course again as I've been paranoid because I didn't go back for the 2nd shot when she was 4. A few days after, I noticed some swelling and didn't think much of it. It's 10 days later now and I still feel a 2-3 cm pocket of fluid/ swelling that moves around top right shoulder blade. I presume the injection site. I have read some swelling is common and I have also read to give it 3 weeks. I wish I had done my research as have now found out that tumours can occur and asking for it to be administered in the leg is much better. I need to call my vet to ask which injections have been administered, what brand and where the injection site was; as I was not there. I thought I was doing the right thing but now I am out of my mind with worry. Cat is fine in general no other problems. I am pretty sure that it is the injection site (top of shoulder) on right, because I know my cats body - I'm always feeling up on her :) and brushing her. This was not there before last week? Do you think that this swelling is normal? It's so stressful for my cat going to the vet.... like you wouldn't believe. She pukes and wees in the car going so, I'm monitoring it right now. I was getting the vet to come my house for 2nd set and I don't even know if I should even do that at all now. Which will mean she has never had that 2nd primary shot. Just to confirm this is a very timid cat, we have no visitors and she doesn't leave my very small garden. She doesn't do people or other pets. She would never go any further as she is basically my shadow these days. To sum up, is this swelling normal? and should she have the 2nd shot after this scenario?

Dr. Michele King, DVM
Dr. Michele King, DVM
1604 Recommendations
The swelling that Tizer has may be a common reaction to her vaccination, especially if it feels fluid-filled and not more solid. It is also possible to get a small abscess at the point of injection. I do not think that you need to panic at this point about sarcomas as it has only been 7-10 days. If it has not improved in 2-3 weeks, it would be a good idea to have it looked at, which you can have your veterinarian do when they come to your house for her 2nd set. I do think it is probably a good idea to have her vaccinated if she is going outside, and Rabies is typically a required vaccination for public health.

Hi, thanks for the reply very helpful. Although I have read online recently that it isn’t a good idea to vaccinate while under or straight after anaesthetic so even more worried now. I asked the vet on the day would it be too much for her and he said no. I’m never going back. I have also just read that 1 dose of FVRCP will usually last a cats lifetime and shouldn’t be given more than once or twice so I’m ok with that for now. If I can get her through this lump. It is 12 days now.

Insomnia isn’t a typical side effect we see from vaccination, normally we see lethargy; however some flea & tick topical spot on products may cause some restlessness.

I just got a stray checked out and vaccinated on Wednesday the 26th, he did fine brougt him inside gave him a bath and went under the bed to hide. He came out later and on Thursday too. Friday he has been under the bed sleeping and purring, but not really coming out to drink and eat which is near by, also nothing in the litter box today (Friday) or last night. He did come out to eat some Temptations snack bites, i also just put his food and water under the bed edge. His eyes look fine can’t tell for hives cause he has very thick hair and is mattedon the undercoat. Wanted to ask if it could be a reaction to the vaccine, i have felt a little sick after receiving a flu shot one year and was thinking could be the same in a way for him, he will be going back in 3 weeks to get neutered, shaved, a broken canine pulled and the booster. They think he is 7 years old and I know no previous about him except we have been taking care of him for almost a year but he dtayed outside, til know when were able to take him to the clinic to be checked. He’s a loving layed back cat whi loves to really head butt our leg for some loving.

Thank you for your question. Without seeing him, I can't comment on whether he may be having a reaction to the vacccine, but they sometimes do develop a little fever after vaccines. If he isnt improving over the next 24 hours, he shoul dbe seen by your veteirnarian, to make sure that there isn't anything going on, and to treat him if he is having a reaction. I hope that he is okay!

Hi, being netured, having a tooth pulled and a booster is too much all at once. I’ve been on this thread because my cat has had a reaction to her shot. I read that anaesthetic and shots on the same day is a bad idea. Just trying to help. Wish I had read something like this before I went ahead and did it. Love and Safety to all kitties.

I understand, he did eat some more of the snack pieces and he does respond, thank goodness he’s not real lethargic just sleeping,,Thanks so much!

I initialy thought it was the feathers he ate from his toy, since they were in his second vomit, but he vomited 6 times since then, and i'm suspecting the vaccine or the deworming.

Some gastrointestinal symptoms like vomiting and diarrhoea may present after vaccination, normally it is self limiting and it is important to ensure that they remain hydrated during this time; however if there is a high fever, chronic diarrhoea and vomiting, loss of appetite or any other concerning symptoms you should visit an Emergency Veterinarian regardless of distance or cost.

Our cat Dash is about a year old and weighs 10 pounds. He had a rabies shot and experienced a severe reaction in the form of loose stool, vomiting and extreme lethargy. It’s been 2 weeks and after two rounds of steroids and antibiotics he is now experiencing skin and ear irritation in a terrrible way. His ears used to twitch and itch previously but now it’s so frequent (but the inner ear is pink and dry). He can’t stop licking or scratching and has formed scabs under the fur. Our vet says it is an allergic reaction to something in our house but I can’t think of what we’ve introduced. I also can’t help but feel there’s a coorelation to the vaccination. Please advise if there’s any specific items we can start eliminating and the likelihood of the vaccine causing issues for this long.

Some pets do have adverse reactions to the rabies vaccine, but it is a requirement in some states/areas/countries and it is in general better than rabies itself. Adverse reactions to the rabies vaccine may occur for a few weeks after vaccination and usually calm down within a month; other causes of irritation like allergens in your home or chemical products can also cause severe itching and other symptoms, try to think if you changed anything (cleaning products etc…) in your home around the time the symptoms presented.

If Murphy's signs are related to the Rabies vaccine, that is a fairly serious reaction, and not common. It would be best to have him rechecked by your veterinarian, as that is not an expected reaction, and he may need medications or therapy to help him recover more quickly. I hope that he is okay!

Ruby had her annual vaccinations on Wednesday morning, it is now Friday evening. She was ok Wednesday afternoon, then very quiet and wouldn't eat Wednesday evening but seemed ok again Thursday morning, although I did see clumps of hair on the floor but it wasn't immediately obvious where from. Unfortunately I have just found a bald patch that is between a 1p and 2p coin in size. The area looks normal skin but slightly sort of grazed (over licking maybe) and is sort of sticky. The patch is at the vaccination injection site (which is an inch or so along the top of her back moving away from the neck). I have just tried to very gently daub it clean with a saline solution made up from 1 tsp of table salt in 1 pint of cooled boiled water. Is there anything more that I can do? p.s. the vet had difficulty injecting her as she was very resistant with claws and teeth out. The vet had to pull away quickly leaving the needle in for at least a minute whilst an assistant came to cover Ruby's head with a towel and hold her whilst the vet then injected the vaccination fluid.

Hello,my male, black, short-haired 3 year old cat went to the vets for his annual booster vaccinations last Friday morning. When we got home he vomited immediately and became unwell. He is continuing to be off his food, though he has tried to eat and then been sick. He's straining to go to the toilet and this has been small amounts of diarrhoea and some fairly normal. He has seen our local vet today and she thinks his condition may be due to the vaccination. She asked about whether he is weeing and I haven't been noticing that he has - watching for this. The vet said he may go out once he is weeing and feed him as normal. The vet felt him and said he was not constipated. He was given 1/2 his usual tea at 5 pm today which he ate all of it. However, at 7.45 pm he brought it all up. That is where we are at with him at the moment. The plan is to keep him in, make sure he has plenty of water. To talk to him to keep him calm and to offer small amounts of food. I now have concerns over vaccinations and how to treat this in the future.
What advice can you give please?

It is possible that the symptoms presenting are a side effect of vaccination, normally vomiting and diarrhoea is self limiting and resolve themselves after a few days without veterinary intervention; however in some cases it may take a little longer. Whilst I understand that you will have some concerns about vaccination, a week or two of some symptoms is a better option than Casper picking up an infectious disease which is preventable by vaccination.

I jus took my rag doll cat to the vet today. We lost his papers we got from the breeder and it’s been two months since we got him. The vet insisted on giving the feline leukemia vaccine. After he got the shot, we came home and I contacted the breeder to give me the shot record and In the contract it said it’s not recommended that i give any of her cats the feline leukemia shot since all of her kittens are negative. It stated in her guarantee that it has been known to be fatal to ragdolls because they are allergic. I am devastated that I have my cat this shot without making sure that he could have it. How long does it take to notice if he is having a reaction? What symptoms do I need to look for? If he doesn’t have a reaction, will he be prone to any other health problems because of this vaccine?

My cat was due for some vaccines (rabies and feline leukemia), and at the time of his exam, it was discovered he had an active dental infection and needed to have some teeth extracted. The vet administered the vaccines at that appointment as we had to schedule out the dental appointment for the next week. My cat had a very bad reaction to the vaccines - low energy and loss of appetite for 4 days. I took him back to get anti-inflammatory and anti-nausea injections after those 4 days as he did seem to be better. He had his dental extractions done and the same symptoms have persisted. He’s low energy, lethargic, barely eating food or drinking water, and because he’s not eating, he hasn’t had any of his antibiotics that were prescribed. He refuses to eat his food if I put any measure of antibiotics in it. I’m worried him having the vaccinations during the dental infection was a really bad idea.

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM

The decision to give vaccines is down to your Veterinarian as they will determine whether an animal is healthy enough to receive vaccination; side effects of the vaccination may persist for a few days and a loss of appetite as well as lethargy is not uncommon after anaesthesia and dental work. If Loki isn’t taking the antibiotics, you may either try to give them by force or return to your Veterinarian for alternative options. Regards Dr Callum Turner DVM

I took in a stray kitten in 2016. He got his 3 vaccinations that year and was fine. The following year, in 2017 he got the same 3 vaccinations and soon after started biting and licking the area of the rabies shot, down to skin. He tested positive for ringworm and was treated for it. But a year later now he still constantly licks hair off , now on the other hind quarter and front legs. The vet called it seasonal allergies and has given Atopica for it. That relieves the itching but it makes his stools runny and the hair hasn’t grown back. These symptoms have been constant so I don’t believe that it’s seasonal allergies. I have not had him vaccinated yet this year.
I’ve also tried changing food and litter.

In some cases, an area where a rabies vaccine was administered may become irritated leading to licking, biting and in some cases a lump may form; if this is the case you should speak with your Veterinarian especially if there is a direct relationship being the administration of the vaccine and the symptoms.

Fever lethargic diarrhea

Hello, My 10 year old cat was tranquilized to get annual vaccine, rabies, and flea/tick medicine last Wednesday.(08/08/2018). She wasn't herself for a few days from tranquilizer, but she was eating food, and drinking water fine. 2 & 1/2 days after the vaccine, she started having diarrhea, (Saturday morning 08/11/2018) but was still eating and drinking fine. But today (08/16/2018) although she seems wanting to eat food, but didn't touch, drank a little bit of water, and then just sleeping all day. she seems to having fever, and became very lethargic, and didn't go to bathroom to pee or poo all day. It's been a week since she got the vaccine, but is there such a thing to have a delayed vaccine reaction like this? This afternoon (8/16/2018) the vet gave her a shot of "anti inflammation". I'm just so worried about her, and I just hope this is something normal after vaccine, and treatable. Thank you very much.

Adverse reactions may occur after vaccination and each pet is different in reaction, some have no issues whilst others require an overnight in a clinic; normally adverse reactions and side effects occur within a day or two of vaccination and are generally self limiting requiring no real veterinary intervention. I cannot say whether the symptoms presenting in Oreo are a direct result of vaccination, tranquiliser or another cause; see how she does after this anti inflammatory and try to hand feed her to encourage appetite.

If he is not eating, or seems lethargic, it would be best to have him seen at a 24 hour clinic today, as they will be able to diagnose him and make him feel better. If you take a video of the behavior on your phone it might help, as cats often don't do the thing they were doing when they are at the clinic !

Hi, my cat had her vaccinations as a kitten then nothing until she was four. I decided to get the vaccinations again, after the booster she ended up on a drip for 24 hours and was very ill. She was also very distressed having to have several blood tests. At the same time she had been given advocate which was out of date (vet advised that this was safe), was it?? I reluctantly got the second vaccine, she was a little ofc colour but seemed ok. It has been a year and it's now time for vaccinations. Should i risk another reaction??? I have read vets follow manufacturer's advice for yearly vaccinations but they only need them every 3 years??? Any advice would be much appreciated. I have two cats who are brother and sister and there was only two in the litter, i wonder if their immune systems are better due to this??

There are mixed opinions on whether or not cats or dogs require annual vaccinations, I recommend following manufacturer’s recommendations since if there are any issues I can always refer to the prescribing information but owners should be informed and be allowed to make their own decisions.

I took my 5 month old kitten to vet to get shots on Tuesday. He was fine yesterday and this morning, just seemed sore and sleepy. He was fine when I left the house at 9:00 this am but when I got home at 3 he was bumping into walls and meowing and walking in his food and water bowl. Seemed disoriented. I of course called the vet and they asked me to bring him in right away. They checked him out and said he could not see. His pupils reacted to light and everything else was intact She said it may be temporary and gave him steroids to see if that would possibly help with the inflammation on his brain which she thinks has caused this. He was a normal, playful beautiful healthy young cat up until these shots!! They gave him distemper and feline leukemia, not rabies. I of course am heartbroken and feel like its my fault that I took him and trusted the vet. I have had many cats and this has never happened!

Dr. Michele King, DVM
Dr. Michele King, DVM

This is definitely not a typical reaction to vaccines, and certainly nothing that your veterinarian could have foreseen. Kittens need vaccinations to stay healthy, and whether this reaction was caused by the vaccine or not is questionable. It would be best to trust your veterinarian, as they would have no way to know that he would react that way, and continue with any follow up care that he may need to get him through this.

No, they did all they could for him. We ended up having to take him to the Emergency Vet where they did everything they could. He started having seizures and walking in circles. It was very sad to watch. The emergency vet suggested an autopsy. He had no reason for the neurological reaction, no lesions, etc. Actually the autopsy showed that he was a very healthy kitten and they could not rule out that it was not the vaccine. I asked the vet to please NOT give him the Feline Leuk on that day and they actually did it anyway. I asked for only what the law required, which was Distemper. I held my sweet boy while they put him to sleep. I am still heartbroken as I feel if I had just taken him somewhere else or if they had not given him the Leuk. vaccine he would still be here. He has tested negative for Feline Leukemia that's why I asked they not give him that vaccine. He was the sweetest, most loving cat I had ever had. Sad.

Hi Negan I truly hope your kitten is recovering. I know how you feel and after watching Ty Bollinger's 'The truth about pet cancer' - no more vaccinations for me (I live in Asia) or my cats. My adult male cat is currently very lethargic (not like him at all!) and limping slightly. Nothing compared to your extreme experience and I wish you well. There's so much we don't know and I mistakenly trusted the standard recommendation to vaccinate annually which is way ott! Every 3 - I'd even say 5-7 years now if at all unless the cat/dog lives in a country where street animal diseases are endemic.

We have had the same issue, we have 2 brother kittens, went to get there shots a few days ago and today we noticed one of them s walking into walls etc.. Has Negan improved at all since posting?

Has Symptoms

Seizures

I adopted a cat 2 and a half weeks ago. 4 days ago he had a feline distemper vaccine. He has had two seizures since (one the day after and another a few hours ago). To my knowledge he has no history of past seizures (he is 3 years old). I of course plan on taking him to the vet first thing in the morning but a second opinion couldnt hurt. Is it possible that the seizures are a reaction to the vaccine? It seems too much of a coincidence not to be related.

Has Symptoms

Diarrhea
Lethargy

My cat got his vaccines 3 days ago and he has had diareah for 2 days. He is very tired and barely gets up. He is 5 months old and he got the rabies vaccine and the beginners shots for kittens. Is this something i should be worried about?

These symptoms are not uncommon to see after vaccination; lethargy, vomiting, diarrhoea, fever, irritation of injection site etc… are typical symptoms seen after vaccination. If Smokie is weak and cannot support his weight, you should return to your Veterinarian to be on the safe side especially with the weekend coming up. Regards Dr Callum Turner DVM

last night my cat got a fvrvp vaccine 2nd one. Today she doesn't want to eat, has no energy, continue sleeping, she looks a little puffy around the eyes, feels a little warmer than usual.I don't see any hives in her body. It bothers her if I touch where the vaccine was given. I have no type of meds for cats at home. This is my first cat. I have her for a month now.

Thank you for your email. Cats will sometimes exhibit flu-like symptoms after a vaccine, as their body is mounting a response to the vaccine. If she is not eating, and seems that she might have a fever, it would be a good idea to have her rechecked with your veterinarian to see if she needs an anti-inflammatory medication to make her feel better and start eating again. You can also try feeding her something that she really likes, like canned food or tuna, to see if that will entice her a little. These signs usually resolve over 24 hours, so she should start feeling better soon. Most OTC medications are toxic for cats, so if you do decide that she needs some help, a veterinarian will be able to get her medications that are safe for her.
