Bunnies all need beds to sleep, whether they have single bedrooms or shared. There needs to be pretty wallpaper and flooring to set the mood.. I like to have a gap between two standard beds then one high , stood up by the ends of the lower beds. Bunnies like bedrooms with lamps/clocks/storage places in their rooms.. Chairs and toys also help comfort. Remember to get bunnies friendly before putting them together.
