Can cats eat dog food?

Avoid

A bite is harmless, but as a diet it lacks taurine and vitamin A for cats.

In multi-pet homes, feed separately.

Why

Cats must get taurine, arachidonic acid and preformed vitamin A from food and need more protein than dogs. Dog food isn't formulated to those levels, so long-term feeding risks heart (dilated cardiomyopathy) and eye (retinal) disease.
