Foods cats can't eat

Cats are far fussier than dogs, but they still get into trouble with food, often through seasoning hidden in leftovers. These are the foods to keep away from your cat. If your cat already ate something, call your vet or ASPCA Animal Poison Control at (888) 426-4435.

Best avoided

Food Verdict Why
Milk Avoid Best avoided. Many adult cats are lactose intolerant, and cow's milk can cause vomiting and diarrhea.
Citrus fruit Avoid Best avoided. Citrus oils and acid can irritate, though a small taste usually only upsets the stomach.
Raw meat Avoid Best avoided. Raw meat can carry Salmonella and E. coli.
Nuts Avoid Best avoided. Nuts are high in fat and can cause vomiting, diarrhea and pancreatitis.
Bones Avoid No. Bones can injure or block a cat's gut, which may need surgery.
Salty snacks Avoid Best avoided. Too much salt can cause serious illness.
Meat baby food Avoid Best avoided. Meat baby food is often seasoned with onion or garlic.
Fat trimmings and skin Avoid Best avoided. Fatty scraps can cause stomach upset and pancreatitis.

Why onions and garlic are the big ones for cats

Onions, garlic, chives and leeks belong to the Allium family. The ASPCA says they can damage red blood cells and cause anemia, and that cats are more susceptible than dogs. They hide in stock, gravy, seasoned meat and meat baby food, so check labels before sharing anything.
