My cat brought in what I believe to be a baby flying squirrel. He is completely covered in fur and his eyes are open. He is breathing normally and I see no puncture wounds. But for some reason he isn't moving and I'm not sure what to do. I have in an old tshirt on a heating pad on low. I tried to give him some pedialite with a syringe but he isn't opening his mouth. There are no local rescues around me and I don't want him too die. How can I help him?
