Cats

Actually, I remember reading somewhere that cats have limited
color perception. To a cat, red appears to be black. Don't know
what green maps to, however...

Note that doing this for the purpose of exercising the cat may violate
US patent 5443036. The patent makes no claims about doing it to entertain
the human and/or the cat, however.

The patent may be invalid anyhow, as it describes using a "beam of
invisible light", which surely won't hold the cat's interest. A beam
of red light works much better. I haven't tried a beam of green light,
but green laser pointer prices have come down enough that it is
tempting to try it the next time I'm in Colorado. (None of my close
friends here in California have cats.)
