Cats can safely eat a few plain, simple “people foods” in tiny amounts, but most of their diet still needs to be complete cat food because they are obligate carnivores.

Key safe foods

  • Plain cooked meat like chicken, turkey, or lean beef (no bones, skin, salt, garlic, or sauces).
  • Small pieces of cooked fish such as salmon or white fish, again completely plain and boneless, only as an occasional treat due to fat and mercury.
  • A little plain scrambled or boiled egg, fully cooked, which can add extra protein.
  • Small amounts of certain cooked vegetables like carrots, green beans, peas, or broccoli, finely chopped or pureed, can add fiber for some cats.
  • A few bites of fruit like watermelon (without seeds or rind) or berries as an occasional treat, mainly for hydration and a bit of fiber.

Foods cats must avoid

  • Onions, garlic, leeks, and chives (fresh, cooked, powdered, or in sauces) can damage red blood cells and cause anemia.
  • Chocolate, coffee, and tea contain stimulants that can cause heart and nervous-system problems.
  • Alcohol, raw bread dough, and large amounts of yeast products can lead to dangerous intoxication and bloating.
  • Grapes and raisins, which are suspected to cause kidney issues in some pets, should be completely avoided.
  • Xylitol (a sweetener in sugar-free gum, candy, and some peanut butters) is toxic and must never be given.

How to offer human food safely

  • Keep treats (including safe human foods) to less than 10% of your cat’s daily calories so the main diet stays balanced.
  • Always serve foods plain: no salt, seasoning, sauces, butter, oil, onion, garlic, or heavy spices.
  • Introduce any new food in a pea-sized amount and watch for vomiting, diarrhea, or itching; stop immediately if you notice any reaction and contact a vet if it is severe.
  • Avoid raw meat, raw eggs, and raw fish unless directly advised and supervised by a veterinarian because of bacteria and parasites.

Quick takeaway

  • Stick to complete cat food as the main diet and use safe human foods only as occasional, tiny treats.
  • When in doubt about a specific food, do not offer it and contact a veterinarian or emergency pet helpline, especially if your cat has already eaten something questionable.
