I am in Florida (not sure if that matters) and found a grown squirrel dragging itself across the road, unable to use its back legs. I have called the wildlife rescues close to me, and they suggested to just release it. There are 6+ cats in my neighborhood, and cannot stand the thought of it dragging itself to its own death. It is currently in a cat carrier on a heating pad, with cat food, water and apple slices. it has taken a few nibbles from one of the apple slices, but really no other movement. Is there anything else I should be doing?? I have taken care of baby squirrels before but never a grown injured squirrel! Please Help!
