We have two indoor cats who keep trying to get outside. This outdoor playpen works well for their needs. There are four ways to get them in and out of the playpen. We put it against our deck, facing trees and bushes. They happily munch on grass and curl up in their baskets when they want to nap. We leave them in the playpen for a few hours and always stay outside near them to protect them against coyotes who are in our area. Easy to assemble.
