Tropical Carnival Natural Behaviors Bio-Treat is a unique daily treat that combines all-natural timothy hay with a variety of flowers, herbs, and leaves to create the ultimate foraging experience for small pets. This grain-free, all-natural treat can be offered freely to rabbits, guinea pigs, chinchillas, hamsters and other small animals, providing nutritional enrichment and stimulating their instinctual behaviors like chewing, foraging, bunching, and organizing their environment.
