Hello, I feed a number of Eastern Gray Squirrels in my backyard and one of them is obviously not well, he keeps falling over whenever he walks and hits his head on things. Sometimes he has to lie down to eat a nut as he has trouble standing upright. He's been like that for 2-3 months now and does not seem to be getting better or a lot worse, but I have no idea what is wrong with him. Unfortunately, here in Oregon no vet is allowed to treat Eastern Grays so there is probably nothing I can do for him, but I would still like to know what is wrong with him. Any thoughts folks? Thank you!
