Crowing
We live rurally - and an outdoor cat is a dead cat - the coyotes get a lot of them. Our vet is part of a TNR (trap, neuter, release) program that adopts feral cats to keep barns free of vermin. As they are already feral before trapping, releasing them is a neutral impact on the environment, except that they can't reproduce. Vet recommends not feeding them, so they'll kill vermin in the barn. If they do head out to catch other prey - they tend to disappear.
There is a program like that near us and many others around the country if anyone is interested in barn cats specifically. We can’t decide. I’d rather get a pair of rat terriers for the barn but I simply can’t have more dogs!
