The vet called and said put him back on Orbax and she didn't need to see him for a couple of days to see if the orbax was starting to work. She said it would work fast.
I did find two odd little bloody pieces of what looked like tissue (flesh) on the bedspread. After that is when there was blood in all his pee. By the time I went to the vet to pick up the prescription, what I thought was tissue was so dried out that it just looked like a piece of seaweed. So it wasn't a stone, but perhaps some tissue that had sloughed off after being passed one? I was in the back of the vet office 2 weeks ago when they had a cat on the surgical table that was completely blocked. Doc showed me the tissue that she took out to clear the uretha. It looked sort of like what I saw on the bed.
BJ, That's a good idea about plastic wrap on the litter box. All I could think of was to express his bladder and I couldn't get anything out.
I don't think I could have anticipated this, He appeared to be peeing just fine, especially since I still had him on sub-q fluids at night, although I'd gone from every night to every other night after he didn't fully absorb it after 12 hrs. I have to go into the office tomorrow so I hope he is ok and doesn't become blocked. There won't be anyone here for 9 hrs.
