This is awesome! Our cat who, as expected, was very unhappy in a harness and leash when out on the deck with us and her dog, is very happy lounging in this playpen. She spends hours playing with a favorite toy, nibbling her cat grass and napping...as long as she has all of us for company and is not left all alone. I don't worry about her getting tangled or wandering off and at risk. It's wonderful. :-)
