Just moved my little one from paper towels to aspen bedding. Tub size an temps are all the same. She is now perched on top of her hides. When I take her down and put her on the bedding she acts like it tickles or something and back up she goes. Is this common? Back to paper towels? The bedding is 1/2" thick. Just for the record, my other one LOVED it when I switched him over.
