I've been using paper towels and they are not as cheap and reusable as you'd think especially if you use them for everything else so I'm on the hunt for a fairly cheap substrate that will be long lasting and is pretty low maintance. I've thought of going back to reptile carpet but once that hting is dirty it stays dirty until you clean it out and it gets dingy after awhile, just not a fan. Then I thought hey let me get some tile but finding a place to cut and getting the correct measurements is annoying. So any other ideas that fit my needs? lol
