I wonder if Qiviut's new "pet" rat snake was resting after a meal and hope that it finds a safe comfortable place outside where it can be useful patrolling for small damaging animals without bothering Q and Mom too much!
Ah, then you are not so negative toward the slitherers as I took it from your post. :-)
Pretty much all the rat snake family (includes corn snakes and so on) are good climbers and some even spend a lot of time in trees, both to hunt, and to avoid predators themselves.
An interesting factoid is that for a given size, king snakes’ constricting strength is about 2x that of their cousins, the rat snakes, or even snakes such as pythons — an adaptation to kill and eat other constrictors, it is thought. A good size king snake is darn strong!
