Green Onions & Cats

All onions, including green onions, are toxic to cats. Even a small amount can make your cat very sick. Onions cause the breakdown of red blood cells in cats, which leads to a serious form of anemia.

In addition, some cats may be allergic to green onions.

Symptoms of Green Onion Toxicity in Cats

You may notice these symptoms if your cat has eaten some green onion:

If your cat is showing any of these symptoms, call the vet immediately. This is a medical emergency. If you know for sure your cat has eaten green onions, then don’t wait for symptoms to appear. Call the vet right now.

Treatment of Green Onion Toxicity in Cats

When you reach the vet, they will perform a complete physical exam on your cat. This will include lab work and possibly other tests.

There’s no specific treatment for green onion toxicity in cats; however, the vet will treat your cat with supportive measures. These may include an IV for fluids and to make it easy to administer medications needed to treat symptoms.

In some cases, a cat may also require a blood transfusion to build up their blood supply.

The good news is that cats who receive prompt medical care have an excellent chance of making a complete recovery.
