This mouse ‘scampers’ only 20cm each time the string is pulled. I had toy cars 30 years ago that moved 20 times as far under their own power.
This is effectively an expensive static toy.

Our kitten/cat likes this toy, but not for very long. It doesn’t move independently for very long which requires us to pull it to make it move again. It would be a lot better if it ran for longer.

I have 1 cat that loves it and 1 that doesn’t, this toy is interactive but the mouse doesnt go for long enough, so you have to constantly keep pulling the ring.

Okay the cat has a lot of fun chasing this but it doesn’t really go that far and I need to keep pulling the ring to make it go again. Only good if you’ve got time to sit there and play. The cat isn’t interested unless I make it move.

I know, it’s a mouse, it should be a cat toy. But my little dog adores chasing this around. I particularly like that it moves and gets my dog moving, fun for inside on rainy days
