My cats are really enjoying this toy! One of my cats is 8 years old but still plays like he is 3 months old. He, of course, loves this toy. My older cat is 10 years old and has become somewhat sedate over the years. However, when I turn on this toy, he chases the laser beams and runs around the toy like he is a kitten again! I love it not only because they are having fun but also because they are now getting more exercise now than they ever have in the past several years. This toy is a keeper!
