Neil asked a good question: if we can tell so much about how animals react in animal testing, why can't Vet. Science give us anything but a completely unspecified answer? I've got no response.
But we've got our little kitten back, and even though in the picture she's got her bandage on, she's managed to take that off (with some help from her parents). She seems happy, and reasonably healthy, and still has an unhealthy penchant for peperoni.
It freaked us out a lot, not knowing and not being able to do anything about it. Plus it's just so expensive to have animals treated. If she hadn't gotten better on her own we were facing another gamut of tests that were more dangerous to her and far more expensive for us. It's hard to know when to stop and when not - talking with a girlfriend she said that her mom would've mortgaged her house if her cat needed treatment. And I just don't know what I'd do when faced with something like that. I have a sneaking suspicion what Neil'd do, because she is his baby. Profoundly grateful that we don't have to face those questions today.
Thanks everybody who commented with hugs - every comment meant a whole lot to me. You all rock.
