Be careful though - my kitty loves it tooooo much. Seriously, I think she is addicted. When I come home from work, after I pet her and make sure all is well, she trails after me while I am trying to get changed and situated whining and crying for playtime. Fine, I toss a few toys, uh, no. Ok, I get the feather wand - uh, meh. Can't be bothered. If I sit down at the computer or on the couch she literally climbs my leg crying until I get the laser.
I have to restrict the play with it a bit since she will race from one end of the apartment to the other until she literally can't breathe. That scared me. Now I am much more gentle in where I point it so she can try to catch it in a limited area and take time outs so she can rest a little. Boy, does she hate it when I stop for awhile.
It is good exercise and stimulating for the cat. But be wise when using it. The good thing is that after a session my baby usually cuddles up for a snooze and I get some peace!
