Onion family plants contain compounds that damage cats' red blood cells, leading to haemolytic anaemia. Repeated small amounts can add up, and concentrated powders are especially dangerous. Baby food has been a source of poisoning in cats because some contains onion or garlic powder.

Can Cats Eat Onions And Garlic?

No: toxic
No. Onions, garlic, leeks and chives are toxic to cats, and the ASPCA notes cats are more sensitive than dogs. They damage red blood cells and can cause anaemia. Watch for onion and garlic powder in baby food, gravy and leftovers.
This guide is general information, not a diagnosis. If your pet seems unwell, or you're worried, call your vet.
Why onions and garlic are dangerous for cats
If your cat ate some
- Call your vet, an emergency clinic or a pet poison line straight away, even if your pet seems fine. Many poisonings are easier to treat before signs appear.
- In the US: ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661. Both may charge a consultation fee.
- Note what was eaten, roughly how much and when, and keep the packaging.
- Don't make your pet vomit unless a vet tells you to; it isn't always safe.
- Use our onion and garlic calculator for a rough guide, and call your vet.
Signs to watch for
- Vomiting and drooling
- Pale gums
- Weakness and lethargy
- Fast breathing
- Red or brown urine
- Signs may be delayed by several days
Collapse, seizures, difficulty breathing or pale gums are emergencies: go to the nearest vet straight away.

Can cats eat chicken cooked with garlic?
It's best not to. Give plain, unseasoned chicken instead.
