Yeah I remember those. I still have one of the very first laser sights ever offered to the shooting public that pre-dates those LED laser pointers. It uses an actual high voltage helium/neon laser tube. I know it puts off some type of high frequency sound that people can't hear, but my cat sure could!
I could flip the switch on and off for just one second, and the cat would wake up from a dead sleep at the opposite end of the house and come running looking for the source of that sound. Had a lot of fun tortur...... err, ummmm.... PLAYING with the cat with that thing.
