Why cats should be on my mind just at the moment, I really can't say. Oh, we've got one here at The Manse alright, but she's such a docile and pampered pet that I doubt she'd be able to catch a mouse, even if it ran across her paws. It was really triggered by my train of thought on seeing the words for my Three Hundred and Twentythird Sentence on Quadrivial Quandary and therefore also The Adventures of Daphne and Maude. The process is perfectly logical. Quantal generally means something which can either be one thing or another: Black or White, Man or Woman, Alive or Dead and that naturally made me think of Schrödinger’s Cat, although the cat is not actually Alive or Dead: it is Alive and Dead, albeit separately.
At School I studied – or read, at least – T S Eliot: The Wasteland, The Love Song of J Alfred Prufrock, Old Possum's Book of Practical Cats – and my favourite of them (I suppose most people's) is

Macavity's a Mystery Cat: he's called the Hidden Paw -
For he's the master criminal who can defy the Law.
He's the bafflement of Scotland Yard, the Flying Squad's despair:
For when they reach the scene of crime -
Macavity's not there!
Macavity, Macavity, there's no one like Macavity,
He's broken every human law, he breaks the law of gravity.
His powers of levitation would make a fakir stare,
And when you reach the scene of crime -
Macavity's not there!
You may seek him in the basement, you may look up in the air -
But I tell you once and once again,
Macavity's not there!
Macavity's a ginger cat, he's very tall and thin;
You would know him if you saw him, for his eyes are sunken in.
His brow is deeply lined with thought, his head is highly domed;
His coat is dusty from neglect, his whiskers are uncombed.
He sways his head from side to side, with movements like a snake;
And when you think he's half asleep, he's always wide awake.
Macavity, Macavity, there's no one like Macavity,
For he's a fiend in feline shape, a monster of depravity.
You may meet him in a by-street, you may see him in the square -
But when a crime's discovered, then Macavity's not there!
He's outwardly respectable. (They say he cheats at cards.)
And his footprints are not found in any file of Scotland Yard's.
And when the larder's looted, or the jewel-case is rifled,
Or when the milk is missing, or another Peke's been stifled,
Or the greenhouse glass is broken, and the trellis past repair -
Ay, there's the wonder of the thing! Macavity's not there!
And when the Foreign Office find a Treaty's gone astray,
Or the Admiralty lose some plans and drawings by the way,
There may be a scrap of paper in the hall or on the stair -
But it's useless to investigate - Macavity's not there!
And when the loss has been disclosed, the Secret Service say:
'It must have been Macavity!' - but he's a mile away.
You'll be sure to find him resting, or a-licking of his thumbs,
Or engaged in doing complicated long division sums.
Macavity, Macavity, there's no one like Macavity,
There never was a Cat of such deceitfulness and suavity.
He always has an alibi, and one or two to spare:
At whatever time the deed took place -
MACAVITY WASN'T THERE!
And they say that all the Cats whose wicked deeds are widely known,
(I might mention Mungojerrie, I might mention Griddlebone)
Are nothing more than agents for the Cat who all the time
Just controls their operations: the Napoleon of Crime.
And it is only fair to mention Macavity's North British competitor, Sam The Skull, written and sung by Alastair McDonald. Sam is The Glasgow Cat and possibly even more than a match for Macavity, at least, so my Cousins in the West say!

I'm a cat, I'm a cat, I'm a Glasgow cat and my name is Sam The Skull.
I've got claws in my paws like a crocodile's jaws and a hied like a fairmer's bull.
I'm no' the kind of cat that sits on the mat nor the kind that you gie a hug
but I'm the kind of cat can swallie a rat or even the occaisional dog.
Noo I used to roam about in Shettleston where they all knew me by sight
"Here's the skull" "here's the skull" you could here them yell as they vanished intae the night
Noo the polis stations all aroond have bars on the windie sills
but they're no to keep the prisoners in they're to keep oot Sam The Skull
I'm a cat, I'm a cat, I'm a Glasgow cat and my name is Sam The Skull.
I've got claws in my paws like a crocodile's jaws and a hied like a fairmer's bull.
Noo I'm no' the kind of cat that sits on the mat nor the kind that you gie a hug
but I'm the kind of cat can swallie a rat or even the occaisional dog.
Noo one fine day no' so long ago they all had had their fill
and they sent for the R.S.P.C.A. to try and catch the Skull
There was naebody could get oot when I was aboot chasin all the weans up the close
Wettlin on the shoes yodelin' the blues and nonchalantly pickin' my nose
I'm a cat, I'm a cat, I'm a Glasgow cat and my name is Sam The Skull.
I've got claws in my paws like a crocodile's jaws and a hied like a fairmer's bull.
I'm no' the kind of cat that sits on the mat nor the kind that you gie a hug
but I'm the kind of cat that can swallie a rat or even the occaisional dog.
Aboot half past two the boys in blue arrived in their Escort van
Right roon the back one had a sack the other had a mallet in his hand
I watched them creep tae the back of the close, Then I casually strolled tae the van
I jumped through the door stuck my foot tae the floor everything had gone tae plan
You can hear them say doon Shettleston way, "What became of Sam the Skull?
He had claws in his paws like a crocodile's jaws, and a heid like a framer's bull."
just you tell them for me that I'm still running free and never a day is dull
It may sound absurd but I'm livin' wi' a bird in a single end in Maryhill
I'm a cat, I'm a cat, I'm a Glasgow cat and my name is Sam The Skull.
I've got claws in my paws like a crocodile's jaws and a hied like a fairmer's bull.
I'm no' the kind of cat that sits on the mat nor the kind that you gie a hug
but I'm the kind of cat that can swallie a rat or even the occaisional dug!
