My cat was very curious about this little nifty gadget. My cat would stare at it as the gadget swirl around on the floor and would chase it around. But the battery shelf life is terrible! I would have to turn off the gadget and let it rest for a good 10 minutes before it power back on and start swirling around. It only last about 5-10 minutes before it stop dead and I would have to let it rest again. I brought one before and it only lasted 1 month before it completely ran out of battery! I only brought another one because my cat likes playing with it so much. So, my final thought is that it is a fun toy that will keep your cat occupied for a while, but terrible battery longevity.
