Petey must be saddened by the loss of his brother. Stress from loss can cause behavioral barbarism, or other compulsive behaviors.
Please ask your vet if Amitriptyline, Prozac, or other behavioural medication might be effective for his compulsive behavior. Amitriptyline can be give topical as a transdermal medication placed on the ear skin. This medication can be made into a transdermal by a compounding pharmacy.
