Yea i know its sounds lame but i dont like how rough the cypress mulch is on them. I feel like it could hurt sliding over it but im sure in the wild they go over worse stuff :p
Where did you order yours from?
Edit: also one more question... Does it clump up when it gets wet? Bc my snakes like to splash their water around in the tubs sometimes making the cypress wet which spikes the humidity on me lol
