Hi... building indoor rabbit habitat!?

Don't use wood or cardboard for the floors in your cage. I built a 2 level cage for my rabbit and I used wood for the second level. The wood is VERY hard to clean and my rabbit decided that that was the perfect place to go to the bathroom. Use some sort of wire floor with a wood frame that will allow the poop to drop through. Carpeting would be bad because the rabbit could chew on the carpet and get hurt on the threads.
