I house my Leo on repti carpet. However, I have 3 paper towels in the cage. One is on his poop spot, one is under his water bowl, the last is where I put the feeders. I remove the paper towel on his poop spot when there is poop immediately after I see it. I remove the feeding paper towel when there is a lot of juice, calcium dust, insect parts on it. I replace the water dish paper towel once a month or after there is a water spill. So how often should the repti carpet be cleaned since the poop and insect parts and calcium never get on the carpet directly?
