My Sulcata just developed these greyish spots on his neck. He lives in SoCal, Ontario, outside. Other than this he is acting normally. Any ideas? He's 15yrs old.
It looks like his shell might be too sharp maybe there's a piece of his shell flaking off and he's rubbed it on it when he looks up? If so you can use an emery board on it or a piece of duct tape but just don't get the duct tape on his skin.
