that stuff works perfict. just make sure you let it dry for a little less than a day, only because the first day or so it holds too much moister. its most likely not going go cause any harm, but there is a small chance of water blisters, but that is the ONLY problem, and its very slim. thats what i recomend just incase you want to be anal.
peat moss may hold too much moisture. Too much moisture leads to scale rot. I use aspen or newspaper and always make sure the humid hides are kept moist.
