Can Cats Eat Tuna?
⚠️ Caution — depends on how it's servedShort answer
Only occasionally and in small amounts — not as a main food.
Why it matters
Plain tuna is not nutritionally complete for cats, and feeding it regularly can contribute to nutrient imbalance and mercury exposure. Cat foods made with tuna are balanced; plain tuna is not.
How to feed it safely
Offer a small spoonful of plain tuna packed in water now and then — avoid oil, brine and seasoning.
Introduce any new food slowly and keep treats under about 10% of your cat's daily calories. Pets with health conditions, allergies or on special diets should only get new foods after talking to a vet.
