ProRep Aspen Bedding is suitable for snakes, some lizards, birds and small mammals. It is soft, dust-free, odourless and highly absorbent and is made from non-toxic shredded wood sourced from sustainable forests. Spot-clean daily and completely replace every two or three weeks, or more frequently if it becomes heavily soiled or wet. If you are using an under-tank heatmat as your heat source do not use a thick layer of Aspen as this may cause the heatmat to overheat. Please refer to the heatmat manufacturer instructions for more information.
