Congratulations! They look gorgeous. You have done really well. Just one small point, I dont want to criticise, just thinking of the wellfare of the bunnies, but do you think it would be a good idea to put some kind of Piece of wood along the ramp so they cant slip off, especially at night. I dont have any wood on mine but my ramps are not quite as high as yours. Rabbits can so easily damage their backs.
