Let's face it, cats have a tendency to get cooped up inside – and the fact that fences and apartment porches do nothing to contain them has something to do with it. You can fix all of the above for your feline friend and take outdoor play to the next level with the Outdoor Mega Kit by Kitty City. It creates a sunny, breathable, perfectly contained space with loads to explore, thanks to a large mesh frame. Interior coves give your cat a break in the shade, and there's a large zip door for easy access for you. A tunnel door lets you extend the fun using a number of other Kitty City sets, or to create a tunnel leading from inside your home to an outdoor play area. And since it's so spacious, it's perfect for homes with two or more cats who could use a roomy feline jungle gym to play!
