If you have small pets like rabbits, guinea pigs, hamsters, or even chickens, this 22-panel playpen is absolutely perfect for giving them safe exercise space! The panels connect easily to create whatever shape you need - square, rectangle, octagon, you name it. We've used this both indoors on hard floors and outdoors on grass, and the stability is great. The included waterproof mat is genius - protects your floors from little accidents and gives your pets better traction than slippery surfaces. The doors make it easy to get in and out for cleaning or playtime with your furry friends. The black metal wire looks clean and is easy to wipe down. We love that you can make the enclosure as large or small as you need by using more or fewer panels. Perfect for supervised playtime when you want to give your pets more room to run around than their regular cage provides. The height is sufficient to contain most small animals without them jumping out. If you're tired of your pets being confined to small cages all day or want a safe space for them to exercise while you're cleaning their main habitat, this playpen delivers fantastic flexibility and functionality. It's become essential for our rabbit's daily exercise routine - she gets so excited when we set it up! Definitely recommend if you want to give your small pets the freedom to hop and run safely.
