Eldest cat: Seeing the bottom of the bowl is not a giant tragedy. Also, stop hissing at everyone. It's getting embarrassing.
Middle cat: I understand that you are clawing my calf repeatedly because you want me to the throw the ball. But, as I have said repeatedly, I cannot THROW the ball unless I HAVE the ball. Fetch means you bring the ball back to me. It does not mean "bring the ball halfway back and then hassle me until I get up and go pick it up and throw it again." Whatever game THAT is, I'm not playing.
Youngest cat: I get that you need to be brushed ALL. THE. TIME. However, there are only 24 hours in the day and I do have other responsibilities. Don't worry, even with a mere 3.6 hours of brushing per day, your coat is lovely, sleek, and stripey.
