What Human Foods Can Cats Eat?
Yes, cats can safely eat several human foods in small amounts — plain cooked chicken, turkey, salmon, eggs, and a spoonful of plain pumpkin or rice top the list. Because cats are obligate carnivores, treats should stay under 10% of daily calories (about 20-25 calories for a 10-pound cat), with meat-based options preferred. Never feed onions, garlic, chocolate, grapes, raisins, raw yeast dough, or alcohol; all are toxic to cats. Most adult cats are also lactose intolerant, so skip milk. When in doubt, offer a piece smaller than a dice cube and watch for vomiting or diarrhea over 24 hours.
Key Takeaways
- Cats are obligate carnivores: their bodies require nutrients found only in animal tissue, including taurine, arachidonic acid, and preformed vitamin A.
- Kittens under 12 weeks should stick to kitten food and their mother's milk — their digestive systems handle new foods poorly.
- Cats with kidney disease, diabetes, or pancreatitis need veterinary approval before any human food, even plain chicken breast.
Explanation
Cats are obligate carnivores: their bodies require nutrients found only in animal tissue, including taurine, arachidonic acid, and preformed vitamin A. That makes plain cooked meats the safest human foods. Boneless, skinless chicken breast, cooked to 165°F with no seasoning, is an ideal treat, and cooked salmon adds omega-3 fatty acids. Scrambled or hard-boiled eggs supply complete protein, but raw egg whites contain avidin, which blocks biotin absorption.
Beyond meat, a few plant foods are safe in tiny portions. A teaspoon of plain canned pumpkin adds fiber that helps with both constipation and mild diarrhea, and a spoonful of plain cooked rice can settle an upset stomach. Fruit is optional at best — cats lack sweet-taste receptors — but one or two small pieces of banana, strawberry, or seedless watermelon are harmless for most healthy cats.
The dangerous list matters more. Onions, garlic, chives, and leeks — raw, cooked, or powdered — damage feline red blood cells and cause Heinz-body anemia; as little as 5 grams of onion per kilogram of body weight can trigger it. Chocolate contains theobromine, grapes and raisins can cause kidney injury, raw yeast dough expands in the stomach and ferments into alcohol, and alcohol itself is toxic to cats at doses under a teaspoon.
Two common assumptions deserve correction. Milk isn't a treat: most adult cats lose the lactase enzyme after weaning, so dairy causes diarrhea, though a thumbnail-sized piece of hard cheese is usually tolerated. And dog food isn't toxic to cats, but it lacks the taurine cats must get from food — a taurine-deficient diet leads to dilated cardiomyopathy and retinal degeneration within months. Canned tuna is fine occasionally but shouldn't replace balanced cat food.
Things to Know
- Kittens under 12 weeks should stick to kitten food and their mother's milk — their digestive systems handle new foods poorly.
- Cats with kidney disease, diabetes, or pancreatitis need veterinary approval before any human food, even plain chicken breast.
- If your cat ate onion, garlic, or chocolate, call the ASPCA Animal Poison Control Center at (888) 426-4435 — Heinz-body anemia symptoms can take 2-4 days to appear.
- Lilies aren't a food, but even licking pollen from an Easter lily or daylily can cause fatal kidney failure in cats — keep them out of the house entirely.
- Bones, raw or cooked, can splinter or crack teeth; never hand over chicken or fish bones along with the meat.
- Tuna packed in oil adds unnecessary fat — choose water-packed and drain it well. Raw fish also contains thiaminase, an enzyme that destroys vitamin B1.
