Spacious Space: Provides 16 square feet of living area for guinea pigs as recommended by vets. Ideal extension of our rabbit cage or independent use. Give small pets freedom to frolic indoors or outdoors Waterproof PVC Liner: The cage liner with 5.9 inches raised sides, which prevent droppings on floor or pee on the wall and could keep the hay and bedding in cage. No more dirty floors Detachable Bottom: The bottom of the pet playpen can be removed, the small animals are closer to nature when used outdoors. The removable bottom can be used as a sunshade cover on the top of the cage to provide additional sun protection Safty Animal Playpen: The distance between the iron mesh is 1.3", which will not trap small animals. Cable ties reinforce the cage for added security.
