but its about to shed...it has his eye caps already (GRAY EYES)...i bought it off a pet shop about 3 weeks ago...its his/her first shed shes 1ft 20in long...i took these pictures today...i don't think their mites either because i haven't spotted any on it

I USE ASPEN SNAKE BEDDING AND I KNOW THATS NOT THE ISSUE...I GOT MY SNAKE LIKE THAT 4RM THE PETSHOP...THE TEMPERATURE IN HIS TANK ARE ALWAYS 80-90....I HAVENT BOUGHT A HUMIDITY GAUGE YET BUT I DO HAVE A THERMOMETER...WHAT I MEAN BY EYE CAPS I MEAN THAT HIS/HER EYES TURNED GRAYISH ALREADY.....
