Well, I just got off the phone with the Vet, and he says everything looks good! I guess there are two things they check to see if the kidneys are functioning properly. At Tubby's last visit, they were both elevated. This time, one is still elevated, but it is at the same level as before (it's not any worse) and the other one has gone back down to a normal level (better than before). And he says the one that's elevated is only slightly elevated, so he's not that concerned about it. As long as I keep giving him the 1/4 of a pecid everyday, the Tubster should be fine. He does want me to continue bringing him back every 6 months though, to keep an eye on things. It's like most everything that the earlier they catch it, the more they can do about it.

Thanks so much to everyone for all your well wishes! It really makes a difference knowing other people care - even though we don't really even know each other. You're a great group!
