Here's a snippet of the poem "Mungojerrie and Rumpleteazer":
> The Rum Tum Tugger is a curious cat,
> He likes to be stroked, and patted, and scratched.
> He likes to be fussed and he likes to be watched,
> He likes to be chased and he likes to be caught.
>
> But Mungojerrie and Rumpleteazer
> Are two of the most mischievous cats in the place.
> They're cunning and clever, and full of deceit,
> They're always up to some kind of trick,
> They're always looking for mischief and fun,
> And they never seem to get caught.
The entire poem details their mischievous nature and their cunning ways of getting away with their tricks. You can find the full poem online, in T.S. Eliot's "Old Possum's Book of Practical Cats," or in the musical "Cats" based on the book.
