Don't use coal tar or phenol products to clean the cage they are toxic. Some floor covering can help clean up. Paper is best this includes news paper. Cedar chips can be toxic. Saw dust and kitty litter can give incurable pneumonia.
All cages require a hiding place and water bowl.
Feeding Snakes will never eat anything but meat. When you can the snakes natal food should be given. Adult snakes should be fed every week. While young snakes should be fed more often. Don't leave a rat or mouse in the cage for more than an hour or it might eat the snake.
