I haven't seen him pee at all for almost a week now. I'm pretty sure he is, and the one or two times I did see him pee, it was very little. There was no smell, no off color, he hunched over a little bit, but other than that, he acts perfectly fine. I haven't been able to see how much he drinks, but someone's drinking a boatload, I have to keep refilling the tub at least three times a week (big tub). On top of that, he's recently developed a lump on his, err...bits. It's right where they attach to the body, right smack dab in the middle of the crease. I can't for the life of me figure out what it is... I gave him 5cc apple cider vinegar the other day, was going to give him another dose today, seeing as how I think it's UC.
