Thanks for all the replies everyone. It turns out the blood from her nose.. I would have known that if I could have calmed down enough to think rationally. For some reason, any sign of blood, I go into panic mode. So, I'm really sorry if i made anyone worry too much.
Apparantly, one of Belle's nails actually ripped out... there's no nail left... I'm not quite sure how she ripped her nail out though... the blankets in her cage are nice and soft, nor do they have holes. And she wasn't playing out on the carpet...but I guess that kind of thing happens though, whether it makes sense or not. Anyway, her vet cleaned the area, and gave or some meloxicam for the pain. She had a slight fever also, but I'm thinking it was due to stress.
Belle hasn't eaten or dranksince the incident at 2... I'm thinking that was due to stress and pain as well. Nevertheless, I'll be keeping an eye on that.
Thanks for your patience everyone.I really do need to think more rationally when these things happen.
