Anyone ever read The Amazing Maurice and His Educated Rodents by Terry Pratchett?
"Bad Blintz is not like other towns.
Something evil lurks here, something that can drive even the most educated rodents out of their minds with fear.
Enter the Amazing Maurice: talking cat, genius con artist, and mastermind behind the greatest Pied Piper scheme in Discworld's history. With the help of a pipe-playing kid and a troupe of strangely intelligent rats, Maurice is prepared to turn this town upside down as only a clever cat can. But it will take all of his cunning and skill to make sure that Bad Blintz doesn't pu and end to their plans ... forever."
