Can Cats Eat Onions? What You Need to Know

Onions are a staple in many human diets, but can they be safely shared with our feline companions? The answer is a resounding no. Onions contain a toxic substance called N-propyl disulfide (NPD), which can cause a range of serious health issues in cats, including:

• Gastrointestinal upset: Vomiting, diarrhea, and abdominal pain
• Damage to red blood cells: This can lead to anemia, weakness, and lethargy
• Organ failure: In severe cases, NPD can damage the liver and kidneys

The Dangers of Onions for Cats

The toxicity of onions for cats is well-documented. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), as little as 1/4 of a medium onion can be fatal to a cat.

The ASPCA also notes that all parts of the onion plant are toxic to cats, including the bulb, leaves, and stems. This means that even if you remove the outer layers of the onion, it is still dangerous for your cat to ingest.

Cooking onions does not remove the NPD, so cooked onions are just as dangerous as raw onions for cats.
