I currently live in ohio and he has spent all summer in this enclosure (comes in at night to a 32"x5' sleep box don't have cover for preditors) there has been no heat light in the hut . I just installed one but these spots were here well before. He was born 2020 according to old owner and weighs...
I have been trying to cure these spots for some time now... I have used the prescribed silver cream from the vet and haven't saw much success. Any suggestions ??
