Yes, they do. Well, I suppose they can hunt for themselves if they are an outdoor cat, but it's important to provide supplementary nourishment should they need it! I have heard different theories depending on the spices of cat over the importance of an all fish diet versus one that has more variety. I tend to agree with those that call for variety as it helps keep a cat stimulated! Unless they are the type of vegetarian based cat found on the planet Gimoria. [Hm, he may be rambling now.]

There's a pet store I can show you. They should have the food that you require. They also have toys you could buy for a cat.
