My neighbor a 1/2 mile down the road (my closest neighbor, fyi) has waaaaaay more cats than that. He cares for all the dumped cats in the area, rehoming kittens and ones kind enough to be handled. Honestly, I've never seen a kitty whisker here at all, day or night. Maybe a 1/2 mile is too far, but I don't think so since unaltered toms have huge territories. My birds are large fowl, but young, and easily 'snack size' for a cat if the kitty was tenacious enough.
