Mine is, too. I had one for my cat, but she never played around much. But this dog knows exactly where the laser pointer hangs and if you reach for your keys, he thinks you're going for it and will run around excitedly and look all over the ground for it. Also, if a reflection from a car shines into the house, he'll see it and try chasing it for the brief second it's there.
Thanks, all, for the comments. Later, QD.
