Our baby is having some trouble with her hind legs - she jumped off the window sil last night and flopped all over the place - we took her into the vet, and there's something wrong with her, but we don't know what. She's at the vet's right now, on saline drip for the day. We hear back in a couple of hours about her x-rays. The problem is that they have no idea what it could be, and it could be a whole host of things that might not show up on an x-ray. We hear back about those in a couple of hours. It may be a permanent condition, it may go away in a couple of weeks, it ... we just don't know.
I'm sorry if I haven't commented back to anyone - won't until we have her back home safe.
