We are thinking about buying a two tier hutch or hutch with attached run to be placed on our patio, so that our new rabbit can be naturally active dawn and dusk. My first question is, do rabbits readily use the ladders in these types of hutches? The next question is, if we chose a hutch with attached run, will thepaved patio be too rough for it's paws. The rabbit will be in a separate run on the grass in the day. One more question I've thought of, do you think the rabbit will be happy on it's own (we plan on getting a buck I think) , or should we think about getting a brother or sister at the same time?:anotherbun
