Pine is a soft wood. The stuff I use for my rats says the exact same thing on the bag.
I would not use it on your snakes.Better to just use newspaper till you can pick up some aspen or cypress.
There is also a product called cell sorb, I saw it in Daytona last year. Greg Graziani was using it i think.

Unless it's a display type of a setup, newspaper is the way to go.
