Dogs may be man's best friend but cats rule. Felines want things on their own terms: to come and go when they want, sleep where they want, and demand attention when they want it – not when we want them to. Cartoonist Gary McCoy captures the kitty humor in this birthday card. Who but a cat can bypass the castle guard to come and go at will through its own special door? Share the humor and let the birthday person know that just like a cat, they rule on their birthday.
