I'll seocnd that- Caleb loves our laser pointer. Ours looks different, tho- it's a little black rectangle, kind of like the remote for remote locks on cars (Ken was given it by some client company years ago).
Although Mocha goes crazy for that thing too I've been told it's not a good idea with dogs. It can cause them to become kind of OCD about moving lights. I know Mocha goes crazy when we get a flash light out now which is so annoying she tries to attack the light and the flashlight itself making any type of power outage really stressful for her because she's trying to catch the light.
As I said with Mocha it's the flashlight but I can see her doing it with a candle I was carrying or a flashing strobe light, or anything else like that. It's not just that she chases it though she's crazy about it and won't quit tries to bite the flashlight and stuff. I can't imagine if I was out camping and she tried to go after someone elses or something.
Yeah, I have also heard stories about the laser pointer making certain dogs OCD about lights. They would become fixated on house lights in the distance, car lights, construction lights, flashlights, you name it. I don't play with Theo with the laser pointer for that reason. Our cat loves it, though.
