How odd that as we are reading and replying to this thread, my problem cat started do the trying to pee here there but nothing kind of thing yesterday morning. Still was doing it around noon so off he went to the vet.

They managed to get urine sample, his bladder wasn't full. Went over his history with the new regular vet. Came home with some pain med to make him relax so he would pee.

Sure enough after 30 minutes or so he went and seems to be fine now. His urine sample came back normal. No crystal everything was normal. So we must be doing something right with his diet. We water down his food so its bit soupy. This forces him to drink more water.

The vet suspect that he may have had a small kidney stone that his body was passing. Pain meds helped him with the pain, relaxed him and he peed it out. Today he is acting normal. All is well except my pocket book.
