I visited the Age of Steam roundhouse, as part of the AC&Y historical soc. tour, this past Saturday, and got to meet Felix, the roundhouse cat. He waited until the end of the tour to make an appearance. The tour guide related a story of when they had brought a locomotive up from somewhere in the South, a half dozen or so geckos escaped from its bowels. Felix spent an enjoyable week dispatching them.
As to getting a shop cat, I would think that a local shelter would have a cat that likes the outdoors available.
