Oh ok. So in reality it's just they dont' know what the hell they're talking about? Because before I heard the reason they push the sand on you is because they make a lot more money if you were to buy the sand off of them (because you need to replace it) then for them to tell you to just use paper towels. Which is the reason I said they don't give a damn about the animal...just making a buck.
Yep. Of course they make more money on sand than they would on paper towels (if they sold them). Most people probably would not trust the pet store employees either if they kept their reptiles on paper towels, or advocated using it in tanks. After all, paper towels are the "ghetto substrate." They may work just fine, but they're not attractive to the eye and they're more maintenance. Both of these factors would turn away customers. Most customers in pet stores are also not there to buy supplies for racks of reptiles either, but simply want to buy a pet for display in their home, and prefer a more natural looking setup. They also more than likely care more about the looks of the tank than their reptile, anyway.
Unfortunate, but most often true.
