So we bite the bullet and bought the "carefresh" wood pulp bedding. I wanted the pellets but Jason said they looked uncomfortable and we could NOT find aspen. So the super expensive carefresh it is. It looks and feel like pocket lint but that is not the problem. Just like everything else in our house she EATS it! Yep she has been eating the carefresh and now is locked in her big travel crate until someone says its safe. Thanks
