T.M.I. Anyway, our snakes have their own personalities, some are chill, some not so much. Until they learn to talk, all we can do is guess, & assume
they have a good reason for being moody.

As far as soiling their sleeping quarters, some snakes don't seem to pay much attention, perhaps because they are still adapted for living in the wild, so when they
"go", they don't stick around. Or to it? (ew!) It's the same reason they don't kill live rodents in their enclosure if they aren't hungry...in the wild, they just move
on, so they don't sense the danger from the rodent.
