All of my animals love later lights. The dogs, cats, (both mine and the strays) as well as the ferret go nuts when we play with them with the later light. Lol.. And for future reference watch playing with this thing outside. I made the mistake while playing with my dog of accidentally shinning it into a full basketball court in a urban area. Needless to say, when I realized where the lazer was shining everyone was gone but the ball.
