I recently posted a question about my boys shedding their hair. It sort of stopped for about a week. Then last night, and today, their cage was a hair factory. Had to vacuum everywhere. Our clothes are getting full of hair aswell, allot more than usual. They 10 weeks old now. Is this normal? Im a first time Rattie owner, but in all my research I do before getting rats, I never came across shedding. Could it be diet? Adult coat coming through?
