All cats, we know, have several names. T. S. Eliot came nowhere near to exhausting the list, though. A perfectly ordinary cat is likely to be given different names for when:
a) you tread on it
b) it's the only animal apparently able to help you in your enquiries as to the mysterious damp patch on the carpet and the distressing pungency around the place
c) your offspring is giving it a third degree cuddle
d) it climbed up the loft ladder Because it Was There and then, for some reason, decided to skulk right at the back of all the old boxes, carpets, derelict Barbie houses, etc, and won't be coaxed out, and then when you finally drag it out by the scruff of its neck it scratches your arm in a friendly way and takes a beautiful leap which drops it through the open hatchway and onto the stepladder, which then falls over, leaving you poised above a deep stairwell on a winter's afternoon while the rest of the family are out.5
It's an interesting fact that fewer than 17% of Real cats end their lives with the same name they started with. Much family effort goes into selecting one at the start (“She looks like a Winifred to me”), and then as the years roll by it suddenly finds itself being called Meepo or Ratbag.
Which brings us to the most important consideration in the naming of cats: never give a cat a name you wouldn't mind shouting out in a strained, worried voice around midnight while banging a tin bowl with a spoon. Stick to something short.
That being said, most common names for Real Cats are quite long and on the lines of Yaargeroffoutofityarbarstard, Mumthere'ssomethingORRIBLEunderthebed, and Wellyoushouldn'tofbinstandingthere. Real Cats don't have names like Vincent Mountjoy Froufrou Poundstretcher IV, at least for long.
The chosen name should also be selected for maximum carrying power across a busy kitchen when, eg, a bag full of prime steak starts moving stealthily towards the edge of the table. You need a word with a cutting edge. Zut! is pretty good. The Egyptians had a catheaded goddess called Bast. Now you know why.
