“The only thing I envy about a cat is its purr," remarked Dr. Blythe once, listening to Doc's resonant melody. "It is the most contented sound in the world.”

“Cats make one of the most satisfying sounds in the world: they purr. [...] Almost all cats make us feel good about ourselves because they let us know they feel good about us, about themselves, and about our relationship with them. A purring cat is a form of high praise, like a gold star on a test paper. It is a reinforcement of soemthing we would all like to believe about ourselves -- that we are nice.”

“I never fancied cats much till I found the First Mate," he remarked, to the accompaniment of the Mate's tremendous purrs. "I saved his life, and when you've saved a creature's life you're bound to love it. It's next thing to giving life.”

“It is a very inconvenient habit of kittens (Alice had once made the remark) that whatever you say to them, they always purr.”

“The most merciful thing in the world... is the inability of the human mind to correlate all its contents.”

“That deep silence has a melody of its own, a sweetness unknown amid the harsh discords of the world's sounds.”
