Ever seen those fics where Akatsuki is turned into cats?
I haven't read them, but this is my answer to that premise.

In case you can't tell, I was drinking vodka when I came up with this.
Please excuse any bad grammar or spelling.

Akatsuki had come out into the open.
Whether it was madness, or a statement to all of their confidence and power, was anyone's guess.

Sasuke had naturally seen this as an oportunity.
To know where his big brother would be. A chance at his vengeance!
He and team Hebi had set off immediately.
Yet now, as he looked on, staring at his brother's much reduced state...
this was NOT what his vengeance daydreams had advertised all these years!

"And you'll all say:
Oh! Well I never! Was there ever
A cat so clever as magical Mr. Mistoffelees!"

Sasuke could swear to feeling pieces of his soul dying with every bounce and spin.
On stage, Itachi continued his role, inwardly smirking.
Lightning flew from his finger tips, the dance continued, the song went on.
He could feel his foolish little brother's anguish and horror.
Sure it had taken forever to corner and get the other akatsuki members drunk.
Expensive too.
It took a lot to get some of them drunk enough to give binding promises to do this.
Not to mention he'd have to sleep with one eye open for the next year or so.

Yet, here, on stage, the taste of his brother's pain and impotent rage made it so worth it.

"A cat so clever as magical Mr. Mistoffelees!"

Itachi in the musical CATS was just to damned funny, I had to write it.
