Short answer

No form of chives is safe for cats — raw, cooked, or seasoned with butter. Chives are alliums like onions and garlic, and all preparations damage red blood cells and can cause hemolytic anemia in cats. Even a small bite of cooked chives could be harmful to a 4 kg cat. Watch for lethargy, pale gums, and dark or red urine over the next few days. Call the ASPCA Poison Control Center at 888-426-4435 if your cat has eaten any amount.

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.
