"My 8 month old kitten loves to play fetch with this. I just squeeze it a bunch of times to make it crinkle, and the sound makes her wild with anticipation, then I fire it off down the hall and she scrambles after it. I don't sleep at night, nor does my cat, so this is a good, quiet alternative to playing with a tennis ball or other fetch toy. I just bought it because it was cute for Christmas, but it turned out to be the best toy she has for quiet apartment play."
