I was just changing the bathing sand and it was half full of droppings as our Degus have slightly misunderstood "going to bathroom". - moment... can the sand be used when repotting houseplants which like sand in the soil, or even in the soggy parts of the lawn? Or is the sand too chalky or something? Sorry, I don't know what mineral it comes from, it's just the general chinchy bathing sand. Has anyone tried?
