This playpen for pets creates a closed area with an open-top where pets can play and move around. You can use this playpen to limit the area where your pets can run around or separate different pets from each other. It is ideal for small animals such as puppies, rabbits, ducks, guinea pigs, rabbits and kittens and is suitable for both indoor and outdoor use. The panels are connected to each other by metal bars, which makes this dog walker flexible and can be built in different shapes such as octagon, square and rectangle in different sizes by adding or removing other elements.
