Iris Ohyama's CI-604E range are your perfect solution for small-sized to medium-sized animals and other family animals! Made of robust and resistant molded plastic, the playpen will last for years and will never rust! The panels fit securely together and can be combined to create a wider/bigger space until 8 panels together. We always prefer a safe environment that we can enjoy together with our furbabies. With the busy days with you, the Iris Ohyama Pet Circle are straight to the point life-saver when it comes to helping your pets to keep them in a temporary secured space and also at the same time protecting your home from avoidable accidents. It is also very functional whenever you need to change your puppy nest or clean your house where it will keep them away from the area where you want to clean. Since the product is collapsible, you can easily disassemble the panels and bring it with you to your trip or move it quickly whenever you want to. You can relocate the product outdoors to slowly introduce your animals to a new place or have your rabbits or guinea pigs enjoy the fresh grasses outdoors. This system is very practical especially when your dog is introduced properly to the cage and recognizes the pet circle as their safe, comfortable place. Manufacturere's note : The puppy play pen is a gradual training solution to improve your dog’s behavior. We always advice to consult a professional puppy trainer before using the play pen. It is also recommended on introducing your puppy to the play pen slowly and safely on which it will allow them to feel comfortable and safe. This way, it will keep them from escaping the play pen and reduce climbing the cage.
