Thanks for the info but I'm really looking for something free, my newspaper and shredded paper are totally free besides the labor to change it out. Typically more than half the cost of breeding rodents is bedding costs, need to keep it at zero if possible. I know Reptichip is really good at absorbing odors, and usually after a couple months in with the snakes it's not too bad, I change it out just to be sure there's no mold and to keep it fresh. I was just throwing it out, then used it for my plants and garden, I'm hoping it will cut my rodent labor in half.
