had my 3 rabbits in this (with a 5t run attached at all times) and it faired very well. I put lino on the bottom floor to protect the wood. I now have my girls in it overnight and I have found they haven't chwed it. The hole fro the ramp will need covering over more, I just attached a small peice of ply wood to make the gap smaller as they did fall down it. If you have trouble with the ramp, you can unscrew where it is secured at the back, add a hinge to the top where it joins the top floor, and make it less steep and also add a tunnel to it as they love tunnels so are not afraid of the ramp. I love my rose cottage, it looks tidy and in the winter I cover it with blankets and a taup folded into shape to cover the hutch and stuck together with duct tape so it doesn't blow about. hth
