I have now bought over this past year 4 interactive toys for my cat. I am very disappointed with these products, they work well for a couple of weeks then don't. I think that the problem is the connection inside the toy becomes loose and then it does not hold a charge. I have high hopes for her latest toy, she loves it and has used it for about 3 weeks now. If it does not last then it will be the last one that I buy. Does anyone else buy these toys for their cats?
