Your guinea pigs pen is an important part of his life, mainly because this is where he will spend the majority of his time. One of the most important aspects of his pen is his bedding. Not only will he root around in the bedding, but he will sleep on it, walk on it, nibble it, and even eliminate on it if he doesn’t use a litter box. Don’t make the mistake of thinking that just any bedding will do for your beloved guinea pig.
