Bilbo and Baggins, being typical gerbils, love their food. They especially love pumpkin seeds, cheese and oatmeal. But, being typical gerbils, they also love to gnaw on things in general. So, we brought them a big gnawing block of their very own like the degus have.

Bilbo is curious too...
We did try to get a photo afterwards when Baggins was actually gnnawing on the block, but it didn't come out clearly enough for him to be made out, so we didn't keep it.
