These are wild cats. They tend to poplulate on farms where there are haybales and grain storage. I know it seems simple to you that have never experienced it - but the wild ones are no different than any other varmit.

my grandparents had a farm, and had feral cats. the difference is they didn't shoot them. a living thing is a living thing.

I'd have to agree....

^^^ IDK, that's a tough one. Its easy to feel bad for cute things, but if you were infested w/ rats you wouldn't hestitate to clean them out.
Not only that, cats are terribly destructive to local bird/ sm animal populations.
So pick your poison, do you like cats or robins/squirrels/rabbits more?
