10 LitreProRep Tortoise Life is part of the species-specific life series of substrates and has beencreated to meet the needs of tortoises originating from arid habitats, particularlyMediterranean and Russian tortoises. It is a blend of ingredients that provides the idealmix of texture and moisture retention to simulate the soils found in their natural habitats.The addition of pure limestone to the mix provides additional calcium if the substrate iseaten. It is also suitable for many species of lizards that originate from arid habitats.Directions:Spread the substrate evenly over the bottom of the enclosure to a depth of at least 2" (5cm)for young animals and up to 6" (15cm) or more for mature animals. Russian tortoisesparticularly may need a deeper substrate as they burrow extensively. Spot-clean daily toremove soiled substrate and replace completely every 2 or 3 weeks. Areas of thesubstrate can be sprayed to provide local humidity but avoid makingthe substrate too wet.
