The Dart Interactive Toy is an automatic spinning laser light which will delight the cat or dog in your life. Plus it"s quite entertaining for people too. Place Dart on a level surface, switch it on and watch the chase begin! Adjustable speeds and timer options offer sixteen thrilling play combos. Our personal favorite is using it to distract the kitties when the humans are going to bed. By the time the timer turns off the Dart, all the humans are snuggled in bed.
