Hi out there. I have been feeding squirels and watching them for years. Just this week I noticed one that comes either every morning or every afternoon and he has an atrophied or injured left front paw. It seems he has lots of trouble getting around and also seems to have trouble eating. Maybe I am just imaging that part. He is smaller,and thinner than all the others. yesterday I built two special shelves on my fence so he wouldn't have to worry about balancing on the fence and holding onto his food. All the other squirrels come to the table on my deck and eat, he just comes to the fence and stays in that area. I don't know about his water requirements or what else I should do to make his life a little easier. I am worried about him, and want to help. Any suggestions? Thank you!
