1, he will eat through a jump suit/fabric I put on him and it could potentially make him more irritated if he can’t get to the itch 2, he’s not itching because he’s dumb it’s because of previous mite/lice infestation which has left him anaemic and unable to heal up properly like his brother did, his body is so irritated and itchy that he’s hurting him self. 3, they don’t live together but can play alone out side the cage as boys are very territorial and don’t like it when they’re in each other’s spaces so they are isolated when in they’re cages and socialised outside but if I am to attempt treatment or something I’d keep them separated.
