i think you mean injested? Eitherway I personally just use newspaper for my snakes, less hassle, and very easy to clean up. I do a couple layers of newspaper and then a couple layers of paper towels ontop of it, mainly for aesthetics, but also because it helps absorb a lot too.
If you're looking for something simple just use some indoor or outdoor carpet. It is easy to clean and can be fairly aesthetically pleasing. You also don't have to worry about the animal ingesting it and developing a GI impaction, nor do you need to worry about heavy growth of potentially pathogenic bacteria or fungi (Mader 2006) as long as you keep things clean and well ventilated.
