All of mine get a soak at least once a week. Especially Slinky, my BCI, because every time I soak her, she poops. Much easier to clean up than in her cage. Both of my Tics have been in shed for the past week, so they've been getting 1 hour soaks twice a day. Some people never soak their snakes, and they do fine. I do it to help keep them hydrated, and keep an eye out for mites. But it isn't really a necessity.
