What is Onion Toxicity?

Onion toxicity results in hemolysis, or the breakdown of red blood cells. As the cells break down, the feline has less cell circulating in the body, creating signs of weakness and panting due to the fact that these cells carry oxygen. Onion toxicity can be fatal in cats if immediate veterinary care is not sought.

Onion toxicity in cats is a hypersensitive reaction of the feline’s red blood cells to the oxidant present in fresh or dried onions. An onion can become toxic to a feline if more than 1 gram per 5 pounds of body weight is ingested. Onion powder has a high toxicity rate and is potentially more potent than a fresh onion. The toxic agent present in onions is caused by the oxidant n-propyl disulfide. 

Symptoms of Onion Toxicity in Cats

The symptoms associated with onion toxicity in cats are paired with those found in an allergic reaction caused by an ingested agent. Common clinical signs noted after a feline has ingested onion includes: 

  • Panting 
  • Elevated heart rate 
  • Weakness 
  • Hematuria (blood in the urine) 
  • Hemolytic anemia (breakdown of red blood cells)
  • Heinz body anemia (breakdown of red blood cells)
  • Vomiting 
  • Gastrointestinal upset 
  • Asthmatic attacks 
  • Allergic reaction 
  • Liver damage 
  • Diarrhea 
  • Decreased appetite 
  • Lethargy 
  • Contact dermatitis (skin exposure) 
  • Fainting 

Causes of Onion Toxicity in Cats

An onion can become toxic to a feline if more than 1 gram per 5 pounds of body weight is ingested. Onion powder has a high toxicity rate and is potentially more potent than a fresh onion. 

Onion toxicity in cats is caused by the oxidant present in onions, n-propyl disulfide. Cats have a high sensitivity for red blood cell oxidation, due to the larger surface area for oxidizing agents to attach to the cell. When the oxidant, n-propyl disulfide is digested and enters the bloodstream, the body interprets this irregular oxidant as a foreign invader. As the oxidant has already attached to the red blood cell and cannot readily be removed, the body destroys the cells in an attempt to remove the harmful substance. The end result is hemolysis, or the breakdown of red blood cells. 

Diagnosis of Onion Toxicity in Cats

The veterinarian will begins the diagnostic process with a physical examination and a review of your cat’s medical history. He or she will ask you cat’s current diet, including table scraps or ingredients in her raw food diet. 

Onion toxicity in cats is commonly diagnosed through the examination of a cat’s red blood cells. As hemolytic anemia is a common clinical sign of onion toxicity, the present of Heinz bodies on the edge of a red blood cell, seen microscopically, will indicate oxidative injury. The diagnostic tool to reveal this clinical sign is called a blood smear, requiring only a small sample of blood from the feline. 

Hemolytic anemia is also a clinical sign of several other common feline diseases, so your veterinarian will likely request a biochemistry profile or radiographs to complete the differential diagnosis.

Treatment of Onion Toxicity in Cats

No specific antidote is available for onion toxicity and the condition is mainly treated with supportive care. The feline may be hospitalized and administered intravenous fluid therapy. The fluid therapy is used to flush the body of the toxin and give the body time to stop hemolyzing its red blood cells. In most cases, once the ingestion of the toxin has ceased, the cat’s bone marrow will begin creating new, healthy red blood cells to replace the previously destroyed cells. In severe blood loss cases, the feline may require a blood transfusion to replenish the body’s blood supply.

Recovery of Onion Toxicity in Cats

Improvement following treatment of onion toxicity will be seen within hours to a day, depending on the cat’s toxic state. Once the feline is stable, the veterinarian may choose to run additional lab work including examination of the blood and urine to ensure the body’s organs are functioning at full capacity. Follow-up appointments are not necessarily required, but the veterinarian may choose to have your cat reevaluated if a blood transfusion was required in the treatment process. 

To avoid onion toxicity in cats, pet owners should avoid feeding table scraps and baby food to the feline. Cats do not usually eat onion by itself, but mixed into a food, it can easily be ingested. Always keep fresh onions, onion powders, onion salts and other products containing onion out of your cat’s reach.

Hi, My cat RoseMary has just recently (As in, just a few minutes ago) licked a slice of flavored bread flavored with both garlic and onion. No actual garlic and onion were on the crust, and it can be inferred that Onion and Garlic Powder were used, and it has come to my attention that both of these powders are more potent. Should I be concerned, granted that there are no symptoms yet and she had only a lick? She IS an obese cat, so should the extra mass prevent anything from getting too bad? Should I Seek Veteranary Care ?

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

Thank you for your email. Onions and garlic are both toxic over time, so the small, one time exposure that Rosemary has had should not cause any toxic signs in her bone marrow. She may have some GI upset, and if she starts vomiting, having diarrhea, or not eating or lethargic, she should be seen by your veterinarian. I hope that she does well.

My cat ate some empanada meet with onions in it!!! Should I contact the vet or wait it out????

My cat (Angel) was around onions all day. We had to make somthing that used 10kg of onions. She was around it wost of the time. Her eyes got all small.

We were cooking at home so we needed 10kg of onions. Angel (my cat) was near onions most of the time. Her eyes got all shrinky. is this ok for a 4 month old kitten?

My senior Cat just ate a half dollar sized piece of cooked onion. Is this cause for great concern?

My 15 year old cat has cancer and has lost his appetite (although otherwise, he still seems to enjoy being with us, so we are mostly force feeding for now). But he seems to enjoy the boxed bone broth. The broth lists onion as an ingredient. Is the nutrition in the bone broth worth the risk posed by the onion?

The small amount of onion flavoring in that bone broth is not going to affect Snoopy's long term health, and if he is eating it and it keeps his appetite up, it makes sense to keep feeding that. I hope that you are able to keep him comfortable.

Vomiting

I gave my cat leftover meatballs. The size of the meatball was about a matchbox and he ate half of it, and stopped eating. Then I gave him his usual wet food, and he ate very little from that too. Maximum five to seven minutes after eating the meatball, he vomited up everything he ate including the meatball pieces. He vomited three times so I'm fairly sure everything is out. I think meatball had onion powder in it. He's a semi-feral cat and now hiding (he hides when he doesn't feel okay). It's not an option to take him to a vet right now unless I tear down my kitchen to reach his hiding place. What shall I do?

Dr. Michele King, DVM
Dr. Michele King, DVM
1370 Recommendations
It is unlikely that the small amount of onion caused Ziggy to vomit and more likely that it was the meatball. If he continues to vomit over the next 24 hours, he should be examined by a veterinarian, but a 12 hour fast after he ate that, which he seems to be doing himself, may help settle his stomach and get him eating again normally. I hope that everything goes well for him.

My cat licked a piece of onion about 45 minutes ago when I pulled it off a slice of pizza. She began grooming shortly afterwards and I googled if they were toxic or not. When I learned they were I got her to drink some water (within about 10 minutes of ingestion) and she behaved normally afterwards. She was playful and active, and after about 15 minutes I fed her at her normal dinner time, 5pm. She ate normally and is behaving normally now, at 5:20pm. When should I bring her to the vet? When will I be able to tell if she was affected by the onion? She really didn’t seem to ingest hardly any at all, it was literally a single small lick. But I want a professional opinion on whether or not I should take her to the vet, and how soon it needs to be. I could take her to her usual vet that I trust in the morning, but if she needs a vet tonight I’ll take her anywhere I can.

A lick of an onion (not actually consuming any pieces) shouldn’t cause any trouble, the problem comes when a cat (or dog) consumed some onion as the Allium in the onion is toxic for their red blood cells and causes anaemia; I would keep an eye on things for the time being and if she starts being lethargic, has pale gums or any other symptom (may take a few days) listed on this page you should visit your Veterinarian.

Thank you for your email. It would honestly probably be a good idea to take your kitten to your veterinarian for an exam, yes.

Your vet will be able to examine her, treat he if necessary, and make her feel better soon.

My 4&1/2 yr old long haired cat seems to have eaten a piece of onion that fell on the floor,and was also caught playing with and chewing on a piece of onion skin. This happened last night (about 18 hrs ago) . This morning we noticed he wasn't interested in his food,there was a couple of small vomit spots down by his litter box,and he has been extremely lethargic all day. we haven't seen him eat or drink all day and we are worried about him. He is much beloved and because we are on a limited budget,a trip to the vet is nearly impossible unless it is absolutely the only answer.He just had his yearly visit last month and was given a great,clean bill of health,and since it seems to have been a fairly small bit of onion,we're hoping that we will be able to get Shadow back to his normal self with just loving care and some time. Is this possible?

Onion toxicity may cause haemolytic anaemia which may result in lethargy among other symptoms; however, it is possible that at this stage the onion has caused some gastrointestinal upset but without examining Shadow I cannot give any assurances. You should monitor him for the time being and ensure that he remains hydrated, however if you have any doubts you should visit a Veterinarian (think about charity clinics) for an examination.

Without knowing more about Alliie, her lab work and what is going on with her, I can't comment on how to treat her, unfortunately. If she is on Doxycycline, your veterinarian may be treating for tick borne diseases, and it may take some time for her to recover as her body restores her blood cells. If she is eating canned food, you can feed her that until she is feeling better. If you aren't sure that she is okay, it would be fine to call your veterinarian and ask what her expected recovery is, and what to expect. I hope that she is okay.

Thank you for your email. Onions and garlic typically cause problems with blood cell counts, but tend to be in longer term toxicities. The small amount that Trooper ate should not cause any toxic signs, but it would be a good idea to monitor for Gi signs. If he is vomiting, has diarrhea, or seems lethargic or not wanting to eat, it would be best to see his veterinarian. In the meantime, it would be a good idea to take the chips away from him.

Hello Drs of WagWalking. I give my cats a varied diet of usually Health Extension Salmon probiotic formula, organic vitamins & lots of water.
A few times lately, I've given them tiny bits (~ < 1 tsp) hummus. This was made with 1/2 lb chick peas & 3 medium garlic cloves. I didn't think the amount would be dangerous but I decided to do better research. This isn't a common event, I've stopped it now. I'm sure they've ingested timy amounts of either onion or garlic in the past via cooked meat dishes, though when I feed them I wash clean all herbs & sauces before feeding them the meat & small bones & cartilage.

Can you advise whether I should give them activated charcoal to induce a detox, or get blood work done to assess possible damage? I've seen no change in behaviour other than the regular mood swings which don't last. Weight is the same. One is nursing and she was always slim.

Their ages vary from 7 months to 6 years. The options your boxes are set up to accept are restrictive & will only let me type in pre-selected descriptions.

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM
2937 Recommendations
If you are not noticing any symptoms in any of your cats and their gums are a good colour (i.e: not pale), you should just keep an eye on them and not give any more food which contains traces of onions or garlic. Most likely the amount consumed (when mixed with hummus) was a tiny amount and wouldn’t cause any issues, but it is wise to keep a close eye for a week to be on the safe side. Regards Dr Callum Turner DVM

Hi Dr. Turner.
Thanks so much for your prompt response. I didn't think to check their gums. They all seem normal. I'm paying closer attention when I give them homemade food now; I'm preparing food strictly for their carnivorous diet. I guess they occasionally consume onion & garlic in minute amounts when they find food elsewhere (when they go on treks etc) but I'll pay better attention to what I give them.

Thank you for your email. It is very nice of you to want to help these cats. Eating even small amounts of onions over time will cause bone marrow problems, so it wouldn't be a good idea to feed them the chicken with traces of onions. If you wash the chicken so that all traces of spice are gone, the chicken should be fine for them, as an occasional meal when there is excess food that is going to waste. I'm sure they will love it!

It is likely that the amount would be small leaving no ill effects for Sergei, I would monitor him for the time being and check his gum colour over the coming days; if you can induce vomiting with 3% hydrogen peroxide, so so to be on the safe side.

Hello, my kitten won't eat and he keeps puking. When i cleaned his puke up, it looked like there were onions in it. What can i do to make him get better? Also, his eyes are goopy and his nose is runny. What can I do for him without spending tons of money at the vet?

If Bruno consumed some onions, it is good that he vomited them up; if you have some activated charcoal at home give him a dose. You should monitor him for a few days and check his gums to make sure they don’t turn pale; if you suspect that Bruno may have consumed something else (which may look like chopped onions) or you’re generally concerned visit your Veterinarian.

My cat ate some meatloaf that had cooked onion in it. She began throwing up and then stopped eating completely. My vet can't see her til Wednesday and I have no vet willing to see her sooner. What can I do to keep her alive until Wednesday? Her gums are white, she isn't even wanting water to drink. Has diarrhea, urine is very dark and appears to have blood in it. She was also nursing 3.5 week old kittens and has since not fed them (I have began bottle feeding them)

Polar Baby sounds very ill, I'm sorry that is happening to her. It is possible that the onion did cause this reaction in her body, and I'm not sure that she will be okay until Wednesday. If you call your veterinarian and let them know that she is in critical condition, they should be able to see her immediately.

My 18 1/2 year old cat has CKD. I mixed some unsalted chicken stock in with her wet food for the past few days, which she happily lapped up. I just found out that there is onion and other spices in the chicken stock. Now she seems lethargic and is meowing occasionally. I give her 100cc sub q fluids every other day. I have stopped the chicken stock. What else can I do to reverse any possible toxicity.? Perhaps fluids daily for a few days?

Onion poisoning has an effect on the red blood cells causing haemolysis, you should keep an eye on the gum colour as pale gums would indicate anaemia (but also reduced erythrocyte production due to kidney failure would also cause the same). Keep an eye on Callie for the time being, but if she continues it be lethargic or gets worse you should visit your Veterinarian to be on the safe side. Regards Dr Callum Turner DVM

My cat Leo ate about a tablespoon of finely diced cooked onions. Does cooking lessen the toxicity? Will I still need to take him to the vet?

When onion is cooked, it does lessen the severity of toxicity but we cannot be complacent; you should keep an eye on Leo and regularly check his gum colour to ensure it stays a healthy pink red colour; ideally you should visit your Veterinarian but if his gums turn white you should visit your Veterinarian immediately.
