laser pointer
Cat's red quarry
A laser pointer is a small handheld device that projects a narrow beam of light, used to highlight points during presentations or lectures.
The bright dot it creates on surfaces makes it useful for directing attention: She used a laser pointer to indicate the data on the chart.
Laser pointers are also popular as toys for cats, who chase the elusive dot.
