Kaorte, hey I am unsure about shop towels the ones I have here at my desk are quite think and heavy. Heavy enough I can't see it sticking to a rat (wet or gory) and being lifted at the same time. I am unsure. Mike has a good idea a friend by me gets roll ends free. If you have a paper converter locally they often have a variety of inexpensive papers on a roll. I use brown paper from one it is a 300 foot roll 24 inches wide for 20$ or so. That is a lot of paper.
no I have not heard of new paper being eaten. It just doesn't 'stick' to objects that are wet. It also is stiff enough to not start to bunch up so it could be swallowed. I corner maybe but that isn't an issue. A sheet is more so. I recognize it is long odds but we both know it has happened.
