I have taken my cat to two different vets in the past two weeks and first he was treated for a unrinary tract infection and now the other vet says he doesn't know what is wrong with him. I brought him in a few nights this past week and he didn't urinate in his cage, so I figured that maybe the medicine finally got through his body. I took him to a groomer today and when I picked him up they said that he has a lot of blood in his urine. I really don't know what to do. If anyone has ANY information on this subject I would appreciate some advice. If it is kidney problems, I would also like to know the procedure or if there is medicine for it and a ball park estimate of how much it might cost. Please help.
