Hi, I found a small male squirrel in they alley behind our home. He was struggling to walk because he drags his hind legs. I don't know if he had fallen from a tree or was hit by a car or just born without use of his hind quarters. I put him in a cat carrier and have been feeding him black walnuts, apples, carrots,and water. We have tried to let him out once, but he still can't use his back legs and his underside became raw. He is very gentle, but I am afraid he will never be able to enjoy the freedom other squirrels have. What do you recommend we do? Is this something you have heard of? Thank you for any help! Pam
