"I got this for my cat when I first found her in summer 2004 (it's August 2007 now), and it remains one of her favorite toys, especially after a catnip recharge. She does indeed "boogie" on this mat: she rolls, gets under it, and generally crashes around. One of her favorite games is for a feather toy on a stick to "hide" under the mat and dart out for her to attack it; she loves to dive into the crinkly-crackly mat to attack (the noise must be satisfying or something). She also loves to discover toys hidden under the mat or to chase off toys positioned on the mat; a lot of times, before I go somewhere, I stage the mat with hidden toys so that she'll have something to play with and keep her active while I'm gone. It's really easy to refill the mat with catnip, too; there's a small zipper you open, and then you basically dump catnip of your favorite brand in, where it catches on a foamlike mat for even distribution. If your cat doesn't like catnip, you could just skip that whole process and still have a crinkly mat (you know how cats love that sound) for your cat to play with. The designs on the mat are great, too. This one's a keeper."
