I'm not quite sure the proper term for it, but essentially what I mean is preventing them from thinking they are going to be fed every time you approach/open their enclosure. I currently own an unsexed (sold as male) BCI who's roughly six feet who thinks he's being fed every time he sees a person and will actively try to strike and eat your hands/arms. He has an incredibly sweet disposition out of the enclosure - he isn't even head shy - he just really, really likes to eat. He goes from an incredibly chill snake to feeding mode the second he's placed back into his enclosure.
While this is completely manageable for me on a 6-7 foot snake, one of my dream reptiles is a Burmese and I fear a big adult with this same behavior won't be manageable at all. Are there any tips or tricks for snakes who just really like to eat to not be so food reactive when opening/approaching enclosures?
