Found out yesterday that nancy (aka the Chubster) has managed to break her femur, right at the top directly underneath the ball joint. She has to go back to the vets for an operation on friday to remove the broken bit so the top of the femur will go into the socket without the ball, apparently there's no other option.
Has anyone else had experience of this in a cat, am worried about how it will heal and how much of a problem this could be for the future. She's only just over a year old! Poor baby.

Any advice welcome!
