If possible, be selective in which cat you ate feeding, or you might end up as a cat hangout. If you already have house cats, they might not appreciate the social or territorial competition. For stray cats any brand of regular cat food works. Also if you ate fish recently the scraps from that meal would be fine. Stray cats don't eat on a consistent basis, so they really would be fine with anything. Water is also necessary.
