I got this product in hope that when I was doing school online my cat would not be bored. The first day using the product my cat loved it.After a few times of using the toy my cat got bored by how repetitive the toy seemed.That doesn’t mean the product is not good my cat gets easily bored with toys and is very lazy. If your cat gets easily bored this is not the right toy for them.At first, our young cat was intrigued…. The toy was fast and she couldn’t quite get her paws on the little mouse before it disappeared underneath. However, that was short lived. After about 5 minutes, the mouse was noticeably slower. I traded the included batteries out for Duracells thinking they would last longer. Replacing with brand new batteries had no affect on the speed of the mouse. It was “stuck” in slower motion. The cat has little interest now except to turn her head because she heard that I’ve turned the toy on ??‍♀️My kitty loves it but you need to by stocks in batteries. The toy just keeps running and doesn't shut off when he's not playing with it. I'm spending too much money on batteries for this toy.Loved this but I did have to super glue the mouse on
