This Fuzzy speaker shaped like a cat shakes their hips better than your own pets ever could, even the ones who studied with the Bolshoi. The included A/V cable connects the speakers to stereo systems, mobile devices, and other music-making machines. Works with the most current iphones and Android Smart phones as well.  The speakers start dancing to the beat once they feel the vibrations, though you can give their weary feet a rest with an on/off switch.
