My ball python has been doing some strange things. Lately when I pick him up he opens up his butt. I'll pick him up and he'll up it, but when I put him down right away he closes it. I don't know why he does this because he used the bathroom yesterday and he even went pee. He has no reason to open his butt. Could he be sick or have worms or why does he do this. My other ball python the new one never does this. Does any one else noticed that there ball python does this. I want to know what is wrong with him. I want to heel him back to 100% just like I did with everything else.
