Re your wife’s workplace: Have they considered trap-spay/neuter-release?
The company doesn’t care, and the people working the gate at the terminal keep ‘em fed, and watered, but they don’t want to get more involved than that, and can’t afford to do that sort of thing anyway. Those security people don’t make that much money.
I’d imagine if the company, a major national corporation was approached for such they would probably do something rash rather than be bothered so nobody does anything other than feed them, and let them be.
Been going on for more than twenty years.
Little Petey is a gem, but I still tell my wife to keep the windows up on the car. We have too many cats as it is.
