its good unles you have cats which would jump into the pen!
also if your bunnies chew on the wood you need to amke sure that thewire doesnt become detached and then the bunny pushes a hole big enoughto ho[p through! ive had that doen many times before!
she jsut hops uo there when she feels like it!thats why the hutch is in the middle so she cant hop out! the littleblanket first was put on theire during the winter to keep the hutch alittle warmer but she seemed to like it so much she kept it into thethe spring and summer as well!
