Can cats eat Onion?
Quick Answer:
Avoid completely. Onions are extremely toxic to cats, destroying red blood cells and causing life-threatening anemia.
Why it matters:
Cats are highly sensitive to sulfoxides and disulfides in onions, which cause oxidative damage to red blood cells. This leads to Heinz body anemia, a condition where the body destroys its own red blood cells. Raw, cooked, or powdered onion are all highly toxic.
What to check on the label:
- •Onion powder in baby foods, gravies, broths, and seasoned meats
- •Shallots, chives, and leeks (also in the Allium family)
Symptoms to watch for:
- •Lethargy, weakness, and fast breathing
- •Pale, yellowish, or blue-tinted gums
- •Reddish-brown urine
- •Loss of appetite and vomiting
When to contact a veterinarian:
Contact a veterinarian immediately if you suspect your cat ate any food containing onion. Do not wait for symptoms, as anemia takes a few days to develop.
