I have had my Grey Tyrion for almost 11 yrs and he has never plucked "knock on wood" but diet plays a huge role in plucking and being given the time to settle in need to be given. My guy hates spray baths showers he prefers to bath in his water dish . Even though he hardly gets wet he sure loves doing it . My cage is 3 ft x 4 ft x 5 ft and is really just big enough for him . He is located in the living room which he loves. And tons of toys and card board for tearing apart .Keeping them busy is very important .
