The Exotic Nutrition Squirrel Nest Box Small Pet Hideout will provide your squirrel with a dry， safe and secure place to nest. Squirrels love to nest and burrow in hollowed out areas， which is why this pet hideout fits the bill! It has holes on the floor for drainage and ventilation， ridges on the inside for climbing， an entrance platform for easy access and a protective metal ring on the opening. If using the hideout outdoors， use a wood protection coating (not included). Fill the box with nesting material to make your squirrel feel extra comfortable (nesting material sold separately).
