I have 3 indoor rabbit rooms, we do not keep any rabbits in hutches, each rabbit room has logs to chew on, toys, litter tray, tunnels to run through making as natural an enviroment as possible for your bunny! All the rooms are heated and designed for house rabbits as these are becoming very popular pets. I have little pens for guinea pigs with toys ,tunnels and logs, all animals are given timothy hay and organic home grown vegetables.
