MMY: This one's for you, perhaps it will soften the blow.
That's Luke's cat, Biscuit, the champion mouse-eater who has never spent a night indoors in his life, and doesn't mind being carted around - upside down, at times - by my little cowpoke.
Excerpt from The Rum Tum Tugger, by T.S. Eliot:
When you let him in, then he wants to be out;
He's always on the wrong side of every door,
And as soon as he's at home, then he'd like to get about.
He likes to lie in the bureau drawer,
But he makes such a fuss if he can't get out.
Yes the Rum Tum Tugger is a Curious Cat -
And there isn't any call for you to doubt it:
For he will do
As he do do
And there's no doing anything about it!
