Toxic Foods for Cats: What Every Owner Must Know

The Most Dangerous Foods for Cats

Onions, Garlic and Chives

All members of the allium family are particularly toxic to cats, even more so than to dogs. They damage red blood cells and cause hemolytic anemia. Cooked, raw, powdered or dried forms are all dangerous. Even small amounts consumed regularly can accumulate to toxic levels. A common source of accidental exposure is baby food, which sometimes contains onion powder.

Alcohol

Cats are far more sensitive to alcohol than humans. Even a small amount can cause vomiting, disorientation, breathing difficulties and dangerously low blood sugar. Never leave alcoholic drinks unattended, and be aware that some foods contain alcohol as an ingredient.

Xylitol

While xylitol's effects on cats are less studied than in dogs, it remains a compound to avoid. It is found in sugar-free gum, candy, some peanut butters and various diet products. Always check ingredient labels before giving your cat anything made for humans.

Raw Fish

Contrary to popular belief, a diet heavy in raw fish is harmful to cats. Raw fish contains thiaminase, an enzyme that destroys thiamine (vitamin B1). Thiamine deficiency causes serious neurological problems. Occasional cooked fish in small amounts is fine, but raw fish should not be a regular part of your cat's diet.

Raw Eggs

Raw egg whites contain avidin, a protein that blocks absorption of biotin (vitamin B7), leading to skin and coat problems. Raw eggs also carry the risk of Salmonella and E. coli. Cooked eggs in small amounts are safe.

Caffeine

Coffee, tea, energy drinks and caffeine tablets are toxic to cats and can cause rapid heart rate, restlessness, muscle tremors and seizures. Keep all caffeinated products well out of reach.

Grapes and Raisins

While more research exists on grape toxicity in dogs, grapes and raisins should also be considered dangerous for cats. The safest approach is to keep them away completely.

Chocolate

Chocolate contains theobromine and caffeine, both toxic to cats. Cats are less likely than dogs to eat chocolate voluntarily due to their inability to taste sweetness, but accidental ingestion still happens. Dark chocolate and baking chocolate are the most dangerous.

Foods That Are Safe in Moderation

Not every human food is harmful. Some are perfectly safe as occasional treats:

• Plain cooked chicken or turkey: safe without seasoning, onion or garlic
• Plain cooked salmon: safe occasionally, not as a dietary staple
• Plain cooked eggs: safe in small amounts
• Plain cooked carrots or green beans: safe as a low-calorie treat

What to Do If Your Cat Eats Something Toxic

1. Stay calm and identify what was eaten and how much.
2. Call the ASPCA Poison Control at (888) 426-4435 or your vet immediately.
3. Do not induce vomiting unless specifically instructed by a vet.
4. Note the time of ingestion and any symptoms you observe.
5. Bring the packaging to the vet if possible: ingredients matter.
