In 2009, I visited a Whisky Distillery in Scotland. They used to have a working cat called Towser, she was an excellent mouser - there's even a statue of her, which you can see here:

After he died, they employed new cats, hoping they would get one as skilled as Towser.

PS. If you ever go there, they also have the most delicious homemade "Millionaire shortbread."
