Just get (a young) one and feed/shelter it.I don't think I've ever seen cats around my neighborhood more than a handful of times over the past 15 years. Not sure if that's due to bigger predators, but I doubt that based on the number of rabbits I see (many of those might be living under my shed).
How do you acquire and train a feral / mouser cat in the first place?
With an older one it's sometimes difficult to keep them from running away to try and get back to their old 'home'. Especially if it is outdoors.
