A couple days ago I came home from work to find Otis, my 1-year-old male cat, continuously going in and out of the litter pan trying to pee. At that point, it didn't appear as if anything was coming out. Also, earlier in the day he had bad diarrhea. I took him to the vet to make sure he wasn't blocked, and he isn't. They did a urinalysis, and his pH level is fine (6). There's no crystalization in his urine, but there was a high red blood cell count. The vet gave me some antibiotics and sent him home. He's been on the antibiotics 2 days and his symptoms haven't changed. As I type this, he's going from one litter pan to the next trying to pee. And it's worthy to note that when he tries to pee, there are little dribbles. It's absolutely heartbreaking to watch this - has anyone else had experience with these symptoms or have any thoughts?
