I always use printed newspaper and I don't have any problems. I personally use 4 sheets per 41 qt tub (2 side by side in the back over lapped a little and 2 the same way in the front). I don't have a problem with bleeding durring misting or water spilss (not noticable anyways). All my adults are set up this way with no hides. They all prefer to hide under the newspaper and move it around as they see fit. The newspaper is free for me though as my mother gets a paper daily and saves them for me when she is done reading them. I was going to switch to unprinted but I don't know if they would hide under it and with one sheet in there they wouldn't be able to bunch some up and hide under some or whatever. And I would have to pay for it so for now I use printed newspaper and I like it![]()
