The Rectangular Panels are Bully Barriers
The Bully Barriers™ panels are very important to the success of the MeowSpace®. They are there to allow your MeowSpace® pet to enter and exit the MeowSpace® without allowing other animals to push their way in during the entering/exiting process. When you receive your MeowSpace®, you will find 4 small plastic square bumpers in the bag with the access tag. Once you set up your MeowSpace®, situate the Bully Barriers™ so that they are just wide enough to allow your MeowSpace® pet through them. Stick one bumper on the base panel on each side of each Bully Barrier™ panel to hold the panel in place. The bumpers come off relatively easy if you decide to change the width of the Bully Barrier™ panels.
