We only use carefully selected substrates from around the world from sustainable, renewable sources that are then heat treated and sanitized. Some of the substrates will work wonders for pets that dig and burrow, while other substrates are just for walking on. Reptiles are found in typically three types of habitats around the world; desert, rainforest, and semi-aquatic and whichever type of reptile, Pettex has the ideal substrate available.
