I completely agree with Skip on the pine comment. I've said it myself over and over again. Pine is safe. I've never even seen a bag of pine bedding in any store marketed for animal use that wasn't kiln dried. As it should be. That's how it's processed.
The only dangerous bedding I've ever found studies on is cedar. I've found studies which state that cedar bedding used with rabbits over time caused certain organs to fail. Of course this couldn't be good for reptiles either so I'd never use it. Pine however, is safe...
Many old school breeders used pine for many years. Still do. The breeders who started this wonderful hobby and passion for all of us. Why? Because it was all that was available aside from cedar. If it was dangerous don't you think we'd know by now??
