Something that I always keep in mind too is that it's good stimulation for them to feel hungry or do do that exploring, strike position, lurking out of their hides thing. Their nature is to be opportunistic, ambush predators so to my mind if they simply get food dropped in once weekly and never feel the need to prepare to hunt, they are missing a vital thing.

We feed weekly but I always enjoy watching the snakes come out a day or two before and begin the searching or lurking behaviours. It makes me feel like they are engaged in life, getting keyed up to feeding night and I think that's a very good thing.
