I've only had my boys a week. I was told they are three to four months old and they are litter mates. I thought they would get along because they were together in the pet shop, but today they were fighting and Smokey seems to have claimed the entire lower half of the cage as his own, preventing Fred from eating, using the litter box, or going into their sleeping space. Fred is stuck up on the shelf with only the water bowl and whenever he tries to come down, Smokey reacts and Fred backs down. I see that Smokey has established himself as the dominant rabbit. I have a vet appointment scheduled for next week and will ask if they are ready to be neutered, but in the meantime should I separate them?
