Oxbow’s hearty, hand-selected Oat Hay is a favorite of many rabbits, guinea pigs, and chinchillas. Our Oat Hay is harvested before the oat develops into a seed, providing savory husks full of flavor and fiber. Its aroma will stimulate your pet’s appetite and encourage him eat more hay. Your pet should have unlimited grass hay every day. GTIN:00744845402703. Free Shipping in the USA!
