Our cat's are on medicated stuff b/c one of my cats, Figgy (male), had problems with his bladder and he had crystaly so he always tells us.He is a good cat, and he only pees on the bed when he is sick, (how convenient) , and Tiggy eats it, too, and when we run out we put them on Dad's Brand Cat food, shaped like stars and is chicken flavor, and then we get medication medicine as soon as we can.
