I am the Hard-Facts Kat!
Hard-Facts Kat? Fancy that!
I does sums, I'm good at that.
Wot does you think of that?
I'm the Hard-Facts Joggers Kat,
Wot does you think of that?
I am the only Kat
Wot can do all of that!
Creature says Enuff of that! 
Or Eccs will say you're a bad Kat.
But I am still the Hard-Facts Kat!
My Friends 
are here, so that is that!

She is the hard-facts Kat!
Now what d'you think of that?
She knows Wot's Wot
and she takes Top Spot
With a bowl of Hills on a special Mat!
Our Gran bought us a big mat each, wot do have a Black Cat on them both and the words A Very Fine Cat Eats Here
