Cat Familiar

Familiar can be any kind of animal, but most common is the cat. One thing you must know is that familiars chose their witch. Per the site, I learned that cats require space of its own, and high quality food.

This fact makes me wonder just what type of cat food is considered high quality. Does anyone have an idea?
