I had to go to an exotic pet shop last week to get feeders cuz my supplier had to work. I talked to the owner a little bit and somehow we came upon the subject of substrate! She keeps ALL of her reptiles on kiln dried pine. She says all the oils are dried out (I've heard this somewhere else, but there was a debate on it). I mentioned how I keep all four of mine on newspaper. She said she didn't like newspaper for substrate because they can't move as well.

I haven't ever noticed a different of how my snakes move on newspaper opposed to cypress mulch. I've never tried aspen, never even thought of trying pine. I was wondering if anyone had ever noticed a difference?
