Nope, those are open on the bottom so it's dirt floor. I just take out the old shavings and throw some new ones in. They haven't used them enough to get them really filthy.I was thinking of something like that. Mine will have to go inside at night and when there is bad weather, too many predators.The thing is me and my dad don't have building experience, but that doesn't look hard. Thanks for showing me. Do you use linoleum or something else for the bottom?
