Pet Supplies Plus No longer carries them. They Discontinued them. They only had 4 balls at Christmas time, that was the last and only time they had any . I bought 2 of them but gave one away. Why can't we order them through you. would be easier that driving all over the place only to find out they don't have them . I have 3 turbo scratchers 2 which have the twinkle balls in them , they are over a year old and still light up. My kids Love them !!! Excellent for all ages !!I have 34 cats ages range from 17 years to 6 months all strays and rescues .So when I find a toy that they enjoy I truly let people know !!
