What can cats eat? A comprehensive, vet-informed guide to safe and dangerous foods for cats.
Cats are obligate carnivores with unique sensitivities. These foods are toxic and must be avoided:
All allium plants are highly toxic to cats — even more so than dogs. Can cause Heinz body anemia. All forms (raw, cooked, powdered) are dangerous.
Contains theobromine and caffeine. Cats are even more sensitive than dogs. Can cause vomiting, diarrhea, tremors, and seizures.
Can cause acute kidney failure in cats. The toxic dose is unknown, so even small amounts should be treated as an emergency.
Extremely toxic — all parts of the plant, including pollen and water. Can cause fatal kidney failure within 24-72 hours. A true cat emergency.
Found in sugar-free products. Causes rapid insulin release and liver failure. Even tiny amounts can be lethal to cats.
Expands in the stomach causing bloating and pain. Fermentation also produces alcohol, adding secondary toxicity risk.
These foods require careful handling — safe in very small amounts only:
Most adult cats are lactose intolerant. Small amounts of hard cheese may be tolerated, but milk often causes digestive upset.
Contains thiaminase, which destroys vitamin B1. Occasional small pieces of cooked fish are fine, but raw fish should be avoided.
Small amounts are nutritious, but too much can cause vitamin A toxicity, leading to bone problems and lethargy.
Cats love it, but human canned tuna lacks essential nutrients and can contain high mercury levels. Use only as an occasional treat.
These foods are safe and beneficial for most cats in appropriate amounts:
Excellent protein source for obligate carnivores. Serve plain, boneless, and skinless.
Rich in omega-3 fatty acids for healthy skin and coat. Always serve cooked and boneless — never raw.
Plain, cooked pumpkin aids digestion and can help with hairball issues. Start with small amounts.
Good protein source. Always fully cooked — raw eggs carry salmonella risk and block biotin absorption.
Safe antioxidant-rich treat. Most cats won't be interested, but some enjoy them as occasional snacks.
Completely safe and non-addictive. About 50-70% of cats respond to the active compound nepetalactone.
