Hey everyone - need some food advice here now. My poor boy kitty had a urinary obstruction last night (He'll be OK - I caught it very early, before he got backed up and very sick so that was good). I really do not want to have to start feeding him Hills..... (or any of the other brands from Menu foods - we don't care if we poison your pets....), but at least one vet tech I talked to is convinced that its the only cat food that work for crystal prone kitties.

Does anyone else know of a good cat food with good ingredients (NO glutens, fillers, junk... preferably no grains at all) formulated for cats prone to urinary crystals? I'd also prefer to keep him mainly on canned, since that is good for cat's UT health as well.
