I've not had my bunnies long but I'm hoping to let them free-range in the living room/kitchen when I'm home soon. I have laminate flooring though and the buns slip on this. In their pen I've just got bits of cardboard down and some vetbed but it still slips around. I'm ideally looking for something that's cheap and also easy to clean as Pepper refuses to be toilet-trained unfortunately. It also needs to be either safe to eat or destruction-proof - I had an old bath mat down but Pepper took a liking to the rubber underneath and kept sitting there munching on it!
