Lilly is a 13 week old mini rex. She has had some major personality changes over the past couple of days. In general, shes more aggressive, digs into the carpet, and stomps her back feet at us often. I'm assuming shes starting to go through adolescence and that hormones are kicking in. She's still too young to get spayed, so I was wondering if anyone had ideas about toys that let her re-direct some of her instincts to dig and bite? She's got a cardboard box fort we made her and a few small chew toys, but she seems much more interested in the carpet and furniture.  

Thanks for any help! 

What are the chew toys made of? My bun likes some variety, especially wood chew toys that have some sort of loofah attached. I also give him old hand towels. Anything with a rough texture works well for us.
