Hey there I'm so glad you decided to post here, it was nice talking with you in the Tripawds Chat room.

I'm not a vet, but what I have learned from talking to orthopedic and rehabilitation therapy specialists, is that when extremely young dogs and cats lose a limb, it is often more challenging for them to learn how to maneuver around. They  haven't developed motor skills yet the way an older animal does, so they will start trying to do things as best they can, usually awkwardly and not good for their body mechanics. 

When it comes to a partial amputation, we see this happen a lot with all ages of dogs. They try to use the stump and then eventually it leads to gait and spinal issues. You  had asked me if you can train her behavior out of her, and honestly I don't know. But what I can tell you is that an evaluation by a rehabilitation therapist may be able to reveal what her future holds with that stump. An amputation correction surgery may or may not be necessary for her to have full function on three legs. The best way to know that is to talk to an expert. And if you decide to see a rehabilitation therapist, the Tripawds Foundation may pay for your first rehab visit so we hope you'll take advantage of that program.

The main benefit to leaving a stump on an animal is if the pet parent is willing financially and time-wise, to train the animal to use a prosthetic limb. Your cat may or may not be a good candidate. An orthopedic surgeon can tell you. Our posts about prosthetics explain more, just click on the link.

I  hope this helps. What's your cat's name?
