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.
Feeding - Western Timothy hay can be fed free-choice to rabbits, guinea pigs, chinchillas, prairie dogs and other herbivores as an alternative to oat hay, brome and orchard grass. Free-choice means that the feed is available at all times. If they finish what you give them, you need to give them more!
