I posted this a while back but only got one response. Since I have tried to find more info on the tail shaking/twitching but can't find anything. Any one else have an idea if this is normal and ok or is this going to be a problem. He has started to do it every time I come in the room. He just shakes at the base of his tail. It started a week or two ago when I was feeding him. Also, my female dragon will at night lay on her branch with her mouth slighly open and drool while she is in deep sleep. Is this normal? Is it bad for her? Thanks again for all of your help, Jacob.
