The Komodo Straw Terrain is a naturally soft substrate, which is due to it being suitable for dry environments. Straw terrain is ideal for use with tortoises and a wide range of snakes and lizards. The Terrain is made from 100% natural straw, this eco-friendly, sustainable and bio-degradable substrate is virtually dust free and will break down to fine particles if they become wet. Also if swallowed they will break down in the same way if accidentally swallowed reducing the risk of impaction.
