The only thing i have applied to him in the cream the vet gave me for my other snake. he said it was ok to be used on any of my other snakes if they have skin issues.
It couldnt have been the temps, i havnt changed any of my routines. it seems as if my other snake passed her issues over to him, they dont ever get in contact with each other and i most certainly wash my hands in between handlings.
the substrate is paper towels.
i do have a dog that sleeps in the room they are in. dont know if that would be a big issue, the dog has been in that room everyday since i got my first snake 2 yrs ago, and never any problem until now.
