My 4-month-old kitten ate a small piece of onion. Is he in danger?

The very small amount of onion powder in this shouldn't cause your cat any problems. He may get some stomach upset due to getting a decent amount of unfamiliar food, but no more than that. If he should become ill, refuse to eat, etc, get him in to see your vet right away.

It is unlikely that Pepper will get poisoned by a few licks of broth with a few crushed onion pieces in it. There is no need to take her to an emergency vet. She would have to ingest a lot of onion in order to get anemia from it. Should she get lethargic or get white gums, have your vet give her an exam, but as I said, it is very unlikely that Pepper will get ill.

Hello, I'm sorry to hear that Luna got into the pan with onions. Generally, she would need to eat a few mouthfuls of pure onion to get a toxic amount. A few licks of oil in a pan with onion in it wouldn't cause problems, except maybe some GI distress from excess fat. If she did ingest a toxic amount of onions, it would cause anemia which results in weakness and lethargy. If you are concerned about the amount she ingested, call her veterinarian and schedule an appointment for a physical exam and bloodwork. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

It depends on the size of the piece of onion, but this normally would not be enough to cause toxicity, so I wouldn't worry too much. The biggest concern with onion toxicity is that it destroys the red blood cells. This takes a few days to happen though. You may notice vomiting when they first eat the onion, but other signs of toxicity won't be obvious until 2-5 days later. Signs of onion toxicity are a dramatic decrease in activity and pale gums. If you notice this, then it's best to have Tabbi seen by a vet as soon as possible. Otherwise, if she is completely normal after a week, then I would not worry about her having any problems related to the onion. I hope that helps and all is well with Tabbi.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about your kitty. Not to worry, just a lick should not cause any problems, she would need to ingest a lot more to cause any issues. She should be fine. I hope this helps!

It typically takes ingestion of about 0.5% of your pet's body weight of onion to be at risk of onion related toxicity. This calculates out to be approximately 0.15 lbs, or around 2 ounces. Unless your pet ate anything close to that amount or more, it is not recommended to do decontamination for him. With a piece of [onion](https://www.petcoach.co/canigive/dog/onions) that only weighs a few grams I would not be concerned. Just monitor him for the next couple of days for any GI upset, lethargy, panting or pale gums. And if he gets a hold of any more you can always contact the [Pet Poison Helpline](https://www.petpoisonhelpline.com/). There is a charge associated with this call.

For this small amount of onion, I think Nova will be just fine. Larger amounts of onion or garlic can cause damage to her red blood cells. If you notice any concerning symptoms, you should have her examined by your vet.
