Can Cats Eat Garlic?
No — garlic is toxic to cats. Cats are especially sensitive to garlic and other Allium plants, which can damage red blood cells and cause dangerous anemia.
Garlic is toxic to cats
Cats should not eat garlic in any form. Raw, cooked, powdered, dehydrated, and garlic-containing seasonings can all cause oxidative damage to red blood cells, leading to Heinz body hemolytic anemia. Cats are considered more susceptible than dogs, and concentrated forms like garlic powder are especially risky.

Why Garlic Is Dangerous for Cats
Garlic is part of the Allium family, along with onions, leeks, and chives. These plants contain sulfur-containing oxidants that can injure feline red blood cells and cause Heinz body hemolytic anemia. Clinical signs may be delayed for several days, so a cat can seem normal at first and still become sick later. Cats are more sensitive than dogs, and concentrated forms such as powders and dried seasonings are often the most dangerous. Because garlic is toxic, there is no safe serving size and it should never be intentionally fed to cats.
- All forms are unsafe: raw, cooked, powdered, dehydrated, and supplements
- Cats are more susceptible than dogs to Allium toxicity
- Garlic can be more potent than onion on a weight basis
- Signs may start with stomach upset, then progress to anemia over 1 to 5 days
- Call your vet promptly, even if your cat seems normal right after eating it
