I have five bunnies, one of which is a brat and doesn't get along with the other 4. The four live in harmony on the first floor. However #5 lives in solitary ... he has the whole second floor to himself so don't feel too badly for him. And I do leave the radio on for him. I've tried several times to have one of the lady buns from the first floor spend time with him but he insists that he wants to be an only child. The radio is my way of compensating.
