I have a paperback I found in a used book store, Do Cats Think? by Paul Corey. (My dad said I would probably open the book and find only "YES!" printed on the first page.) It was first published in 1977, and I suspect it's long out of print. Corey cites many events in his long acquaintance with felines as evidence of ratiocination in cats, even suggesting they are superior in humans in some areas, as their minds aren't cluttered with a lot of extraneous information.

Anyway, I've identified "I'm watching a bird," "I'm hungry," "Stop working on the computer and pay attention to me," "Stop knitting and pay attention to me," "It's time for my brushing," and "I want a treat NOW!"
