It's the worst kind of substrate you can use for a Ball Python. It retains absolutely no water, therefore it cannot be used to aid in humidity retention for your snake. It also can't absorb any or your snakes urine, so when its urinates, it is forced to literally lay in its own waste. gross

Take the advise of the above members, and do what’s best for your snake. Change the substrate. Just because you don’t feel like you’ve had problems doesn’t mean your snake wouldn’t be better off with a different substrate.

Since when did the absolute bare minimum become ok?
