Little One Mountain hay is a naturally grown sundried grass. Little One mountain hay has a rich botanical diversity; it provides essential fibre necessary for dental health and proper digestion. As we all know, hay makes up a major part of the dietary requirements for all herbivorous pets (guinea pigs, rabbits, chinchillas, degus). It is vital to provide your small animals with unlimited access to hay. Hay can also serve as perfect bedding and entertainment, as your small furries can burrow and forage in it as well as creating a cosy den to relax in.
