Are cooked chives in a sauce just as toxic as raw chives for cats?

Short answer

Yes, cooking does not destroy the toxins in chives. All forms—raw, cooked, dried, or powdered—are toxic to cats because they contain compounds that damage red blood cells and can cause life-threatening anaemia. Even a small amount mixed into a sauce is dangerous. If you suspect your cat ingested any chives, contact your vet or the ASPCA Animal Poison Control Center at 888-426-4435 immediately for advice.

An allium, like onion and garlic. Damages red blood cells and causes anaemia.

Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.

Chives should not be given to cats at all. Even a small amount can do harm, so there is no portion small enough to be safe.

Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.

Why these cautions matter

Garlic and onion damage a pet's red blood cells and can bring on anaemia. Signs are often delayed for several days, so looking fine straight afterwards does not rule it out.
