Lasted 5 Minutes
My two kittens enjoy playing with these mice... but the pleasure is short-lived.
The first mouse I gave them lasted 5 minutes. Then the fabric was ripped and the filling came out.
The second mouse lasted 2 days. Then one kitten was playing with the filling lump and the other with the outer fabric.
The six pieces lasted under 2 weeks, not worth the money.
(Maybe it's ok if you have a sedate senior cat who does't play vigorously.)
