I know ball pythons are supposed to be lazy and stay in their caves a lot but that's not what I'm talking about. For the past couple days he's been acting very slow. He's hardly been moving at all. It's at the point where I have to open the cage and pick him up to make sure he's not dead. And even when I hold him he just sits there acting stiff as a rock. The only time he'll move is when I'm holding him in a position where he's uncomfortable and will wrap himself around my arm. I'm getting very worried about him. I've had him for a couple weeks and I know it's normal for him to not eat for the first few weeks but the last times I've tried to feed him he'd move away from the mouse and try to avoid it. This time he sits there and stares blankly only moving ever so slightly if the mouse touches his head. So is this a problem? Do I need to take him to a vet?
