As it turns out, the pc guy will be here tomorrow. Our schedules just didn't mesh today. I went upstairs to check on Puddy a little while ago and if I hadn't seen it w/my own eyes, I wouldn't have believed it: she peed right in the sink. She isn't acting as though she has a UTI; she finished up a round of Zenaquin about a week ago. I don't know if she can't control her bladder or if she just didn't want to walk down the little steps to the litterbox or what. She's been using the litterbox fine up until this incident. This is getting serious.
