Was putting back my BP's freshly replenished water bowl today, and he's been rather antsy lately because of the two sizes too small rats he's been eating as of late since I bought them in bulk when he was smaller (he just finished the last one yesterday and I have the appropriate size for him ready for the next feeding so don't worry ). So as I was putting the bowl back he was rearing up in very obvious hunting behavior, so I took a step back and remembered the "protocol" I've taught him ever since coming home. Tapped on his hide a couple times and he immediately stopped and ducked his head back inside to allow me to place his bowl down without any complications.

You could argue the tapping merely spooked him and broke his concentration, but considering I've made it a habit to do so every time I approach him in such a fashion whenever his enclosure is intruded upon for any non-feeding reason, I do genuinely believe he has enough know-how at this point that the tapping was enough to have him recall the meaning behind it and respond accordingly.
