Can cats eat garlic?
No. garlic isn't safe for cats and shouldn't be fed on purpose.
Why
Like onions, garlic damages red blood cells and causes hemolytic anemia in dogs and cats. It's more concentrated than onion, so even small amounts are risky.
What to watch for
Weakness, lethargy, pale gums, vomiting, diarrhea, dark-colored urine.
What to do
Call your vet if your pet has eaten garlic.
For cats specifically:
Garlic is toxic to cats just as it is to dogs.
If they've already eaten some, don't wait for symptoms
This page is not veterinary advice and is not a diagnosis. It's a general reference for a common food, and it can't account for your pet's size, age, health conditions, medications, or how much they actually ate. Toxicity is almost always about dose. If your pet has eaten something you're worried about — or is showing any symptoms — call your veterinarian, an emergency animal hospital, or a poison control hotline right away. Never induce vomiting unless a veterinary professional tells you to.
