Josh and I went to visit her at the hospital tonight. She seemed to be improving, and was very happy to see us. She was rubbing and purring and generally being more responsive than she has been the last couple of times I've seen her.
They've been force-feeding her in an attempt to get her to eat, which makes me sad. But the more important thing is that she's been keeping it down, and everything GI-wise seems to be working. So, once they can jump-start her desire to eat for herself again, she's allowed to come home. This could be as early as tomorrow. I'm cautiously optimistic, but trying not to get my hopes up too much.
Still no indication of what could have caused this whole episode. We're going to throw out all her open food and treats and tidy the place up, just in case. Oh yeah, and us? TOTALLY looking into pet insurance.
Once nice take-away, I suppose, is knowing that otherwise, she's a perfectly normal and healthy cat. It sucks that all those tests had to be done for nothing, but knowing that there's no reason she shouldn't be with us for a few more years makes it somewhat worthwhile, at least.
Go, kitty, go! Eat, kitty, eat! We want you home so much!
