Does your reptile's terrarium have a certain indescribable stank to it? This revolutionary substrate by Zoo Med is made for the stinkiest of sand dwellers, like bearded dragons, leopard geckos, uromastyx, and other notoriously nasty poopers. They can dig in it, burrow in it, and of course let loose their disgusting bowels in it. The natural clay substrate helps to dramatically reduce and even eradicate foul smells. So if your tired of having your olfactory senses offended, or embarrassed to have company over to the house, give this a try and eliminate the funk.
