Most with a wood floor use wood chips. You will have to decide how you want to do cleaning. Many on this site use the deep litter method. I started with that, but it didn't make me happy. Now, I use just a layer of chips and shovel out completely every week or so- depending on weather. Also, if you have a droppings board and clean that each day and pick up piles of poop in the chips, the chips will stay clean much longer...You can always add another layer of chips, just for a quick spruce up. Good luck!
