This might be a silly questions but I wanted to ask it as I am curious...My 5 week old Foxer, Petey has a VERY active and wiggly tail. Much more than I've ever seen with any of my other squirrels. As soon as I start talking to him his tail starts going crazy, not really in a pattern or rhythm but all over. And he'll wiggle it for about 5 minutes then he calms down... What does this mean?
