Our lucky cat waving and waving and waving, if you donated her every now and then a new battery. The gold-colored cat is made of plastic and therefore very light. The "angle" mechanism seems very fragile, however, he works perfectly. Even after a fall of one meter from the window sill on the living room floor beckons still. Also, our "Small" has got the cat ever to grab .... Is just a lucky cat, even that they survived.
