Timothy hay is the most popular choice of hay for small animals. It is high in fiber, which is essential to small animals’ digestive health. It is also more coarse than other hay and helps to wear down small animals constantly growing teeth. Orchard Grass Hay is an excellent addition to your small animals’ diet. It has a softer texture and a sweeter taste, making it appetizing to picky rabbits. Timothy and Orchard Grass hay are ideal for guinea pigs, chinchillas, and rabbits.
