Quoted from alexis

Because ... ?

While I can't give anything that proves this song is autobiographical, it's theme of someone happy on the outside but torn apart on the inside fits more with the way he perceieved himself (Help!, I'm Loser etc) than any complaints he had against Paul (which were more about his musical talents and straight laced attitude.)

Quoted from alexis

Because ... ?

Well now you know that your
Cat has nine lives babe
Nine lives to itself
But You only got one
And a dog's life ain't fun
Mamma take a look outside

As John was a cat lover , he makes this observation of his cat and then applies the verse to himself i think ?

Quoted from DaveRam

Well now you know that your
Cat has nine lives babe
Nine lives to itself

..number nine....number nine....number nine...

But seriously, while it may be just an observation of humanity in general, I can't see anything to indicate that it's about Paul.

I think its Arthur Janov psychotherapy gone rockabilly.

I think it's a commentary on hypocracy... but it was most likely spurred by his feelings towards Paul.. just like how do you sleep was later admitted to be about himself... especially lines like "you can comb your hair and look quite cute" he always seemed to attack Paul for being the cute one.

Quoted from Bungalow Bill

I think it's a commentary on hypocracy... but it was most likely spurred by his feelings towards Paul

I think you're right: it began as an attack on Paul before broadening out into a better song about hypocrisy. Too bad something similar didn't happen with "How Do You Sleep:" it remained an anti-Paul diatribe.
