Thanks everyone, I just got back from the vet and its not so good news. Not so good b/c this is pretty serious and not totally bad b/c at least they don't have to amputate or anything.
She dislocated her right leg and on the x ray there was a microscopic chip almost, couldn't really tell. They said it may be able to pop back in but it may just pop back out and plus she would have to wear a leg brace thing for a few weeks which is not going to work with her not being the type of cat to even wear an e-collar, and plus I won't be home to watch her.
My other option which is what I am going for is surgery. They are going to cut a part of her muscle since the vet said that small dogs and cats don't use much weight on their back legs as much so after they heal, they wouldn't notice the difference, and are back to normal since they have so much muscle back there.
I can't believe I let this happen and I feel even more horrible b/c this is going to be like $600-$800 which I dont even have $ for right now but the most important thing is that he said the doctor may be able to work out some sort of payment plan.
I almost cried at the vet thinking how much pain she is in. I have to drop her off at the vet tomorrow morning so that the doctor can look at her and do the surgery if all is well. This couldn't of happened at a better time, I am soooo broke. Before I had my credit cards to fall on but now I don't even have that! Sorry about the long post....
