Thanks to all of u for the positive info. Orangino is around 2 or 3 years old, he was rescued by a dear friend last year along with his sister Orangina, also missing a leg! Orangina currently lives with my friend Glenda and Orangino is with us. Orangino is a very active young cat, under supervision he even attempts to hunt!! We purchased kitty stairs to help him get on the sofa and bed, although he insists on jumping off rather then using them. One of Ornagino's hind legs is a little shorter then the other, that's the one he doesn't use much, it's also kinda boney. The other hind leg is also short but offers him some cushioning, that's the one he uses most. He seems totally ok with his disability, sometimes I think it bothers me more than him.
I promise some photos real soon.
