my python just shed the other day, while i was holding him acually. he started digging his head into my hand, adorable lil guy. So anyway after he finished i sprayed him with reptile vitamin spray, now the next day i look and it seems like some of those little squares here and there are spots of shed that have not come off. They look like a little faded dots. I soaked him and after about 4-5min i rubbed it a bit got nothing...any ideas? i tride getting pics but they do not show up in the picture.
