Ahhhh I do see the problem. He got his cord and some gooy stuff wrapped around his leg which would cut the circulation of not giving him the proper blood flow causing the foot to basically shrivel up like that.
Even if he was to survive he would be permently crippled, he wouldnt be able to walk so he would have to be confined to one place. Breeding it would not be possible, plus you wouldn't want to breed him could cause the young ones same issues or similar issues. He or she would be a house pet...
