Yesterday I noticed something very worrisome about my 3 year old pastel ball, Banana (Banana S'mores to be exact). You know how balls have those fat parts toward the backs of their heads? Well, his are GONE. It's sort of squishy and now I am really worried about him. His weight is fine, he hasn't been losing drastic amounts (he's been fasting for the winter so he obviously hasn't been gaining any). There are loose parts of the skin where the fatter parts used to be on his head and there aren't any other areas on his body with loose skin. I have emailed the reptile vet I know with the pictures I'm going to attach to this but I wanted to know if anyone has experienced this with their ball??

Please help!

PS, his humidity is fine, as well as his tank... nothing has changed so I don't know what's going on with him!

PSS, sorry the pictures are kind of blurry... if you look hard enough you can see where it looks sunken in
