I wanted to update that I spoke with his doctor this morning. She said the blood in his urine and the having the urge to pee is normal right now until his inflammation goes away, his surgery was not even a week ago.

I asked her about the thickening of the bladder wall and if she thinks its inhumane to have him live like this and she said no, we just have to find a way to manage it.

She is open to trying the Elavil or Clomicalm again, but wants to wait til he is healed so we can really see if he is going to have the urge to pee once his bladder heals.

She is real happy the fountain worked and he is drinking water too.

Anyway, I wanted to thank everyone for their input! I knew you guys would understand my situation and concern! Thanks a bunch!
