He is indeed on paper towels. It's helping a lot that I can see if he's gone to be bathroom also, I feel a lot better knowing he has some water in his system. I would take him back and ask for a culture, but I don't have any money for another visit. Luckily one of my good friends works at the vet I go to and is going to talk to the doctor about it for me today along with show him some pictures. If it comes down to it, and the vet asks for me to bring him back, I will find the money somewhere, but I don't want to take him in to have them say "oh it's okay it does this before it gets better" or something and then have something go really wrong and not have the money to take him in then. I live with my parents, (I'm 17), and my dad had an accident and is on workers comp right now. So, it's very tight. I used some of my graduation money for the last visit.
Also, do you know how I might be able to tell if he's in pain???
