Unfortunately this is a pretty big vet hospital and they are pretty busy. I don't think they encourage visiting hours! Anyway, the vet just called and Rocky is doing pretty well. The labs they did earlier weren't to check his renal function so they won't know if his kidneys are improving until after they do the labs late tonight. On the positive side, he is eating and drinking and to me that's a good sign. Any time he isn't feeling well that's the first thing we notice, his appetite drops. Fingers crossed----------------------
