There's prior art, too. I used to tease my cats with a HeNe gas laser 
back in the early 1970's, long before laser diode pointers were common.

I also recall being at a convention of science fiction fans in those 
days, and, from a balcony ten stories up, teasing *people* entering and 
leaving the hotel. Of course, this was before the appearance of an 
unexplained laser beam implied the possibility of a firearm at the 
source end...
