I've been treating my squirrel for MBD with tums for a few days now. He seemed to be getting better, but when I just got him out to feed him, he was freezing and wouldn't move. He is on a heating pad and he sometimes moves his tail sporadically. I think he's having seizures. He's about 8-9 weeks old. He's been eating powder puppy formula and taking tums with water about every 4 hours.
