That's too funny. I took Bob to be micro chipped a few years ago and in the examining room they had painted grass around the bottom of the room and Bob tried to bite it too. They are more observant then we give them credit for.
Bob sounds awesome. I read your story about him wrecking the wall and leaving a poo trail up into your decking! I'd love a monster, a real 50-100lb beast, but with us renting, and the crappy Scottish weather, it's not ideal just now. Maybe when my lotto numbers come up I can get a custom house built just for some reptiles. That's the dream anyway!
