I haven't used a lot of cypress, so I can't really answer that in any useful way.

I'm using Kaytee at the moment. The shavings are definitely not very large. My hatchlings at ~150g were on it without issues.

Does it matter if it says "kiln dried" or would any ole' pine will do?

I will admit that I've avoided pine simply because of people saying that it is toxic etc. Since a lot on this forum have used it for decades I think it must be safe for snakes. Do you know if it is only snakes or is pine safe for other reptiles as well?

Also, all the pine I find in these parts available in bulk are huge pieces, meant for horses. I wonder if that is ok or not?
