Summer is in full swing, and chances are your playful pussycat spends many hours gazing out the window at all of the wildlife. While bugs, birds, and squirrels are everywhere, she is safely indoors. But you can bring a little of the outdoors inside with Butterfly Ball. This plastic ball was designed to spin and flutter in the air just like a butterfly. To add another level of stimulation, you can fill the inside of the ball with the catnip that is included in the package.
