Oh cats. When I first bought my homestead-ish like place it was chuck full of mice and pack rats. Solution? Cats. Easiest solution? A couple feral cats from a nearby town my dad lived in.
Easy solution problem. Dad was happy to help. Not with 1 or 2. No, he started with 7. If I hadn't stopped him, he'd probably still be delivering cats weekly. Didn't matter. Two of the 7 made it through a year, 1 of those is still with me. Once they are wise enough to avoid being coyote appetizers they breed like mad.
So after a couple of years I now have 9 cats. Probably 20 in the spring. I even have cats that show up out of the blue I've never seen before -- mostly males in the spring looking for love but also females who just wander by and stick around.
Slowly getting them fixed/neutered as I can live trap them and run them through the vet who has a humorous disposition about the situation. They definitely know when the BBQ or food hits a dish.
I have had them dump cats out here that were in birth and one that had just been fixed and was still knocked out from the drugs!
