We keep catching our tarantula Eric cartman chewing on it’s tank in a variety of locations. Is our pet testing the sturdiness of its enclosure or is it just something they do? I am not going to lie it makes me nervous that a fang could become injured or it could injure a human? Eric Cartman is also rearranging substrate than proceeds to hang out on the wall with the low temp heating pad. We used a paint brush to move Eric but he just lets us brush his legs and doesn’t move. I will say Eric Cartman is a good eater.... he is a big fan of crickets. Any similar experiences with this species?
