Yes the double act version is not very satisfying, the basic material is promising but I couldn't find any formulation that really worked.
The one liner leaves the audience to do the work dissecting cat-owner, and makes the 'even' meaningful - not only does she not own a cat, she doesn't even like them. For this it becomes risky but I prefer it to the original. But then I suppose I don't really have any context about KK which you suggest in your response. And as I said its only because it's always at the top of this page that my mind has been tugging at the seams!
Sharia Law, didn't she do that 'girls just wanna have fun' song?
