My cat was grabbede by a dog and he shook her in his mouth her back legs were not movimg. We took nher to a mvet and they said her hip was brocken.. we took her to a hospital to get her fixed but they said she wasn't well enough for surgery they would wait a week.its been a week and they've had to force feed her and she is not going to the bathroom by herself they have to do it for her. Is there any possible way she is going to get better

Yes it is possible that you cat can get better. You did the right thing by taking the cat to a vet for treatment. As you can imagine there is a lot of stress for the cat having a bowel movement and with that kind of injury nothing your saying is unusual at this time. All you can do at this time is trust your doctors that have her. It does sound like they are doing their best. Good Luck.
