Foods That Are Always Off-Limits
Onions, Garlic, and All Alliums
Every member of the allium family — onions, garlic, leeks, scallions, chives — is toxic to cats. They destroy red blood cells and cause anemia. This applies to all forms: raw, cooked, and powdered. Cats are actually more sensitive to alliums than dogs.
Chocolate and Cocoa
Like dogs, cats are affected by theobromine in chocolate. That said, since cats typically have little interest in sweet foods, cases of chocolate toxicity in cats are less common.
Grapes and Raisins
Can cause kidney damage. The exact toxic compound hasn't been identified, but the risk is real enough that grapes and raisins should be avoided entirely.
Alcohol
Even trace amounts of alcohol are extremely dangerous to cats and can cause liver and brain damage.
Foods to Approach with Caution
- Milk and dairy: Most adult cats are lactose intolerant
- Tuna (in excess): Feeding large amounts long-term can lead to mercury accumulation and nutritional imbalances
- Raw fish: Contains an enzyme that destroys thiamine (vitamin B1)
- Liver (in excess): Too much can cause vitamin A toxicity
- Bones: Can splinter and injure the digestive tract
