Stewie made it through the drive to the vet this morning and is doing fine. He was in & out of the litterbox a lot less last night, and he's been peeing a little bit here & there. The vet wanted to get some urine to send to the lab for tests, but apparently Stewie wouldn't cooperate with that. So, we got some Albon tablets to give him every 24 hours, and the vet said if he doesn't seem to get better in a few days to bring him back in. So far today he's been fine, not in & out of the box hardly at all. I hope this means he's in the clear...or at least getting there. We'll definitely keep an eye on him these next few days!
