I took him out again, and the vet had a quick look. He said his bladder doesn't feel big or hard or anything which is good. But he did an x-ray or something and there is a lot of "grit" in there He said if he doesn't pee by tomorrow then it's a problem...and of couse, the vet is closed tomorrow so that will be another $100 just for the visit. He said they will have to do it all over again, and if it comes back yet again, then there is the surgery. I told him I really can't afford that. He just look sorta sympathetic. I really don't want to go through all this just to have to put him to sleep in the end. I know that's a mean thought, but...
