Hi
it was his back leg he lost. It's just a nub at the moment, several people have suggested it may grow back.
He seems to have become fairly "tame" very quickly which is a worry for releasing him again. He recognises the long stick I use to put food in front of him and when I open the lid to feed him he sits up and looks around for food.
*edit* I meant to say, it's coming up for a fortnight since his accident and his leg is fully healed. Yay!
