Hi, my 8.5 year old Carpet Python has strange marks on him and he is having a bad shed. It has generally always had a good to perfect shed but for some reason he has these horrible patches on him and he is shedding in bits as it’s breaking at these bad patches. See photos. Thanks in advance for any help. 
I don’t actually know if he is a him or a her.
