Calcium Sand or "Calci-Sand" is a substrate made from calcium carbonate and either sold in its natural grey colour or with added colours for a more decorative finish. If a healthy, well supplemented animal accidentally eats small amounts it should be passed in the animals normal bowel movements. At Internet Reptile we no longer keep any of our own animals on calci sand and we advise careful research before you choose to do so. It is imperative that if it is used all aspects of your husbandry are perfect so any potential risk is minimised.
DID YOU KNOW: There is a wide market for calci-sand which expands far beyond reptiles... this extends not only to other pets but even arts and crafts.
