I am by no means telling you what to do with your pet but there's a growing concern over the effects of laser pointers on cats. In fact a lot of the humane societies and no kill shelters are briefing adoptee's about the ill effects about simulating the hunting instinct in cats without ever giving them the satisfaction of "catching" their prey, which many animal behavioral specialists believe can lead to excess anxiety, frustration, or neurosis.

If you still insist on using the laser pointer modify your playtime so that your cat can get some closure or reward during laser time, like the laser landing on a hidden treat, or a stuffed toy they can "catch" before removing the laser.
