That's hilarious, the way his beautiful boa just won't stay still- like he's determined to steal the show.
He finally gets around to discussing "color" around 10:00, btw.
In noting the way many snakes defecate as soon as we clean their cages he makes an interesting point, that maybe boas are "marking their territory" this way? Personally, I think it's more likely that it's just the activity & minor stress of interacting with us that causes them to "go" (& NOT some evil desire to mess up what we just cleaned, either, lol), so if you ever think your snake might be constipated because he hasn't gone in a while after eating, keep in mind that even before you try giving them a "soak", try handling them a bit more first. Just don't put on your finest dry-clean shirt when you do.
Yes it's quite funny how his first boa really won't keep still.
I find alot of pure locality boas are more active than the boa imperator morphs personally
