Thanks for all the help. I do give both of my cats canned food, just not every day. Probably once or twice a week. Favorites seem to be Fancy Feast and anything with fish or chicken of some other brands. Tuna fish out of the can when I make sandwiches is a big hit as well.

Absolute no-no favorite for both cats is chocolate milk. If my kids don't put the glass away, one is dipping its paws in to drink out of it.

It never hit me as a UTI as he has been using the litter box.

And yes, I'd rather put the money into canned food than a huge vet bill.
