The Coir Wonder Small Animal Bedding is derived from coconut husk (coco) chips and this versatile material offers numerous benefits for a variety of small pets, including bunnies, rabbits, hamsters, snakes, lizards, geckos, pythons, tortoises, turtles, frogs, tarantulas, guinea pigs, ferrets and more. Coir Wonder Bedding Material comes with a pouch of our own Active Odor Control System made from Steam Activated Charcoal made from coconut shells. Excellent substrate for small animal enclosures: The fibrous texture of coco chips allows for effective moisture absorption, helping to maintain optimal humidity levels within terrariums and cages. It is to retain moisture without becoming excessively wet preventing problems of mold and fungus.
