Hi. I just wanted to tell you that I have a tripod, too.. My Colby is missing a front leg. He's had 2 surgeries. The first one left him with a stump, and he still tried to use it all the time. The second surgery took the stump as well as his shoulder blade.. He walks much better, and can even run up and down the tall cat trees with the rest of my cats. I would recommend you check into having her whole leg removed. It will make for a much easier life for her!
