Actually that's a great idea and I've suggested it, with the change that the snake bags then go into plastic bins for several reasons:
- Extra security in case the snake escapes the bag (it happens),
- The bin will prevent your sheets from getting dirty if the snake pees, and
- My dogs sleep in the bed too so if the snakes are in bins they won't get stepped on or smooshed by a German shepherd if they're protected by the bins.
