The word "cat" was included in the title only because that's what was used in the original article.
That being said, I have no information as to any experimentation that may or may not have taken place involving coffee beans and domesticated house cats.
Thank you for your attention.
I just had to post to say LOVE your tagline.
Also cute kitteh, or civet or mr. coffee or whatever it is!
I would never give coffee to a cat. Poor thing might only sleep 20 hours a day.
