I, too, have a cat that must have wet because of urinary tract problems. He loves his wet, though, and his dry. In fact, he will eat almost anything! Did I mention he could lose a few pounds?
For cats that have Uurinary tract problems but won't eat wet, there are many dry foods out there that address this problem. My boyfriend has a cat that won't eat wet. We've tried everything, but she will only eat dry. Oh well, she's healthy and that is what really matters! As long as they are healthy, it shouldn't be a problem.
