Harlan Tekland Envigo Aspen Bedding for Pets #7093 Product description 7093 Teklad shredded aspen bedding is made from 100% Great Lakes aspen wood. It makes an excellent contact bedding for rats, mice, hamsters, gerbils and guinea pigs. 7093 Shredded aspen is not a by-product of some other manufacturing process. It is manufactured from pure aspen wood, specifically for use as a contact bedding, from aged virgin timber. 7093 Shredded aspen is a natural hardwood material, so it is a preferred alternative to softwood bedding materials such as pine. Also, unlike traditional hardwood chips, the random particle sizes of shredded aspen material give animals the ability to construct nests and burrows. This makes 7093 shredded aspen a good choice for use with breeding animals. In fact, 7093 shredded aspen is the bedding material that is most widely used in Envigo animal production barriers.
