ToysOpoly Pet Playpen - Indoor/Outdoor Cage Best Exercise Kennel Your Dog, Cat, Rabbit, Puppy, Hamster. Portable Water Resistant Fabric Pen Easy Travel 24x24x17 (Blue)Category: Dog Pens KennelsA pet playpen is the best and way to train your puppy or cat in a fun yet safe space, protected from anything potentially harmful. Managing your young pet at home while you are outside, or even inside, can be tricky, even with an attentive “puppy proofing” of all the rooms. For those who do not know how sturdy and strong this playpen is; it can withstand cats jumping on it, big dogs running against it, and this soft playpen took every challenge perfectly without a scratch. This is an indoor portable exercise pen, and would better suit small and medium dogs. Giant breeds would probably not feel very comfortable in it. One of the main features is the speed at which it unfolds for set up and how fast you can fold it back into the case. It is the best option for traveling, especially for holiday rentals. The carrying case is included. The bottom panel is zipped so you can take it off and wash it as often as you want plus, everything has been built using water-resistant materials which helps if you have it set up outside temporarily.
