These little toys are terrific, but we take them away at night - otherwise we hear crinkling all night long. My cat loves the bright colors and when we throw them they "bounce" in unexpected directions to keep her on her toes. We have one that plays fetch, so we love that this is easy to find so it doesn't turn into a game of human fetch. Sprinkle a little cat nip onto then for a little extra fun!
