Onion toxicity in cats is commonly diagnosed by examining a cat’s red blood cells.

Your pet can receive a blood transfusion, intravenous fluids, and medications to control vomiting and diarrhea if necessary.

Onions are dangerous for your cat to eat. If he eats even a small amount of onion, it is advisable that you seek veterinary assistance quickly.
Onion toxicosis is much more common in dogs than cats, but it is because cats are pickier about what they eat. Your cat is unlikely to chew on some raw onion.

For example, baby food, which may contain onions or garlic, can be a particular problem for cats. And remember, some cats are not that demanding.
Now, if your cat eats a little of a food that contains onion, every now and then, he doesn’t need to panic. It’s going to take a lot and usually regular exposure to onions or Allium species over a longer period of time. So for cats, just be careful to avoid exposing your cat to anything that you know contains or has the potential to contain onions.
