Can cats eat dog food?

⚠️ Caution — conditions apply
A stolen bite is harmless, but dog food can't replace cat food — cats need taurine, arginine, and more animal protein that dog food lacks.

Cats are obligate carnivores with specific needs — especially taurine, an amino acid dog food doesn't provide enough of. Long-term dog-food feeding can cause serious deficiencies like heart and eye disease.

Did your cat already eat dog food?

Frequently asked

Is dog food toxic to cats?

Not toxic, but nutritionally inadequate. Cats need more protein and specific nutrients like taurine that dog food doesn't supply in sufficient amounts.

My cat keeps stealing the dog's food — is that a problem?

An occasional theft is fine. If it becomes their main diet, deficiencies can develop, so feed them separately and make sure your cat eats its own complete food.
