As the mother of two wonderful gerbils, I have found a way to make bedding last a lot longer. Our gerbils love to chew on cardboard tubes. (as I'm sure other small animals do also) Anything from paper towel tubes, to the tubes around aluminum foil. My husband and I always save any tubes we can find for the gerbils. So I just put a little of the store bought bedding, and then put in many tubes. The gerbils love chewing on the tubes, its good for their teeth, and it provides extra free bedding!
