a. a. milne wrote a cat poem

Yes. The author of Winnie the Pooh wrote a cat poem. I had no idea. (By the way? Christopher Robin was based on Milne's own son, with whom he had a fraught relationship. Christopher drowned himself as an adult. All very sad. Sorry 'bout that. P.G. Wodehouse wrote a searing parody of Milne in a couple of his later short stories.)

Upon reading this poem, it becomes evident that only Milne could have written it:

Pinkle Purr

Tattoo was the mother of Pinkle Purr,

A little black nothing of feet and fur;

And by and by, when his eyes came through,

He saw his mother, the big Tattoo.

And all that he learned he learned from her,

"I'll ask my mother," says Pinkle Purr.

Tattoo was the mother of Pinkle Purr,

A ridiculous kitten with silky fur.

And little black Pinkle grew and grew

Till he got as big as the big Tattoo.

And all he did he did with her.

"Two friends together," says Pinkle Purr.

Tattoo was the mother of Pinkle Purr,

An adventurous cat in a coat of fur.

And whenever he thought of a thing to do,

He didn't much bother about Tattoo.

For he knows it's nothing to do with her,

So "See you later," says Pinkle Purr.

Tattoo was the mother of Pinkle Purr,

An enormous leopard with coal-black fur.

A little brown kitten that's nearly new

Is now playing games with its big Tattoo...

And Pink looks lazily down at her:

"Dear little Tat," says Pinkle Purr.

Awwww. Reminds me of the still-nameless, the still-technically-homeless kitten.
