[Question_Assumptions]

One of our male cats was straining while we lived in Japan so we spend a few hundred dollars getting him checked out. He and the oldest female cat we have now both get the Hill's Science Diet cat food for cats with urinary problems. The other three cats we have (all siblings) don't seem to have this problem, though sometimes the cats eat each other's food. It was easy enough to notice something was wrong for an indoor cat (he was acting strange). You were lucky that you found your kitty in time.
