I'm so confused! I've read many contradicting things about which substrates to use for BPs.

As I've posted before, I have very recently adopted an adult (5-6y.o) female BP.
She has always lived on pine shavings- but some sources advise against using pine.

Next time she needs a bedding change, is it in her best interest to switch to something else? At the petstore I found two products made by ZooMed, one was specifically called "Snake bedding" (I believe it was aspen?) and the other was Cypress mulch which looked a little "chunky" lol. Would changing her substrate type cause her stress?

I'm very paranoid about her health and only want what's best for my girlie.
