Ask A Pet Pro

my cat is apx 14-17 yrs old.  i think she has dislocated her back leg (from the hip).  she is not able to walk, or stand, but the foot is fine and she can move it.  however, now she is not going to the bathroom either.  no pee or poo since yesterday. i believe she is in a ton of pain.  can you please tell me how much a visit like this would cost?  can anything be done for her without a traumatizing visit to a vet hospital?
