Oh no! Im glad they dont have to operate but, man not knowing is so awful. I hope you find out what is wrong and he gets better soon. Poor guy, poor mom.
Annejelynn, he has been peeing blood, crying, and going in and out of the litter box every five seconds. This has been going on since he was about a year old (he is about 4 1/2 now). We have tried everything. Special food, medicine, frequent cleaning of the litter box, a water fountain (to make sure he drinks enough). We just put him on another food. It's called Wellness.It is probably the best food on the market and it has cranberries in it. I hope it helps, otherwise I don't know what to do.
