Tinkie was playing with one of the other cats on Saturday night while I was making supper for everyone. Something happened and she hurt herself. At first I thought she had pulled a muscle or something like that, so I put her in my office on Sunday to limit her mobility. But she wasn't getting any better so I took her to the vet this morning. It turns out that she fractured her femur near the head (where the femur bone goes into the hip). She is only about 3.5 years old so she is very very young for something like this to happen.
She is going in for surgery tomorrow, so please keep your fingers crossed for her.
