Substrates...?

[Sean_.E.]

Hey,

I am thinking about swiching a couple of my animals (leopard gecko and African house snake) over to a new substrate.
I currently have my house snake on newspaper and my leopard gecko on paper towel. I want to get a subsrate that my african house snake can burrow into because they like to do so. For my leopard gecko Im just looking for alternative to paper towel. If I can't find a better substate for the gecko, It's not really a big deal.
The snake on the other hand, well I think he need something better.

Also can someone tell me a little more anout this Carefresh and bettachip stuff?

Thanx
Sean
