Our fun, edible forage tray is made from wood fibres combined with vegetable extracts and alfalfa which are pressed and dried, creating a gnaw that's as hard as wood without the risk of splintering. Ideal for adding your own treats for further enrichment, but comes with wood and alfalfa-based edible gnaws. Ideal for rabbits, Guinea pigs, chinchillas, degus, rats, hamsters, gerbils and mice.
