A ball of yarn? That's so last century. FroliCat Bolt is a $20 interactive laser toy for your feline pal. Place the bowling-pin-shaped device on the floor or hold it in your hand, and drive Mittens to distraction with the laser patterns it emits. In manual mode, you can aim the Bolt any which way to create unique laser patterns. In automatic mode, the Bolt will turn off after 15 minutes--about the limit of nonstop, fruitless chasing, pouncing, and batting at phantoms you can hope for from even the most gullible cat.
