"I know it says chinchilla on it, which may deter gerbil owners, but gerbils absolutely love this. Make sure you buy the "sand" rather than the "dust" however becuase it is more coarse and will not interupt their breathing airways, yet still penetrates their fur. I put some down in their play pen like a little sand box. Their natural enviornonment is the desert, so they def. know what to do with it instictively. It leaves them so soft and fluffy! You'll love to watch they way the roll around in it too, adorable. P.S this stuff is all natural and non-toxic. :o)"
