This sustainable grass paper nesting material can be used by all rodents and also birds. For the production of grass paper, 50% of the pulp from wood is replaced by grass fibers, which is beneficial to the conservation of resources of trees. The grass paper absorbs moisture and retains heat, so the rodent can sleep at a comfortable temperature. Due to the pleasant inherent odor, the grass paper is readily accepted by the animals. Of course, the hamster nest is edible.
