I feed my Kingsnake every 4 days, roughly per page 383 recommendation of the Hubbs book. On this schedule, she's ready to poop 3 days after each feed (1 day prior to the next). So what I've been doing is taking her out of of the cage on the 3rd day for some handling, during which time I put her into the bathtub. She hasn't missed yet doing her business crawling in the tub on this schedule, and cleaning really isn't much of a problem.
