yeah, I think Tim is correct. Plus, in nature, these animals live a MUCH MUCH harder lifestyle. They are constantly looking for food, as it never comes at regular "intervals" for them. They are hardwired to want to grow fast and hunt all the time. But your little guy has realized that it has a good thing going. Its stumbled on to a cache of good eatin'!! Why expend energy to go find food, when it simply comes by every other night?
And just because the snake is hiding, don't assume that it doesn't know EVERYTHING that goes on in and around the cage. Because it does.
Sounds like you're having fun with your Cal King though. They are GREAT snakes. Post a pic if you get a chance!
