Hello, Scully and Rascal love their fleeces, they are Ewan's old baby blankets, for my new babies! I put newspaper under and the fleece on top and lots of toys on botton level, but Rascal likes to move all the fleece around and hide under it! Is it ok for them to be on the newspaper? When I kept pet rats it was a bug no no cos of the ink? Dows anyone have a tip to hold the fleeces in place?
