ashleycat.... i have 6 rabbits. the three adult rabbits are seperated. they live in a large cage in a tack room in our barn. you can seperate you buns by putting them in cages. if they are allowed, you can let them out so they can play with each other while they are supervised. since your buns are inside and litter box trained, im not sure how to keep them seperated, and run free at the same time
