Please help!! So our beardie 'Buster' is acting VERY strange this morning! We have a piece of sandstone in his cage to help him shed. Well this morning he is biting it, almost like attacking it! We can hear him grinding his teeth on it even... we've never seen him behave like this before, so we're a little bit concerned. Idk if it's a sign of agression, or if he's lacking something or what?!... we have a log in there also, and as I'm typing this, he's biting his log also. So it's not just the sandstone. My daughter just picked him up and held him and he didn't show any signs of agression towards her, bit as soon as she put him back in his cage he started biting at things again....
