I had to pick up Hadley the other day during her free time running around because she was pulling on the carpet. Afterwards, it looked like there was a stain on the carpet that she was chewing at, until I took a closer look and saw that, in fact, the 'stain' was actually the bottom of the carpet showing through because she had actually pulled out a patch of carpet fibers and (presumably) eaten them. Luckily the carpet in that room is old and needs replacing anyhow. I think I will get laminate there next... surely she can't manage to eat that...
