My boys are indoor bunnies in my lounge. I have wooden floors with some pieces of Lino & cardboard down that the rabbits seem to sit on all the time now the weather is colder. Obviously the floor is cold & I don't blame them for not wanting to sit on it, however, I am wondering whether it would be ok/safe to give them a dog mat/bed as this would be softer & not cold to sit on?? They are chewers of wood but not so much of other things, they have never chewed the fleece blankets they have but my curtains have definitely suffered!
