Just a quick note -- I can hear Audace playing with the StarChaser. If I look at him or get the camera and come back, he'll stop, so I'm just enjoying the sound (and once in a while, a peek!) while he plays!
I ordered these from Petco, and I'm very pleased with the results. Now to figure out where to get replacement light-up balls so maybe Audace will play "soccer" or something!
