Well, get your own!
I wouldn't mind importing a few to my piles. Ever since my neighbor's cat croaked, there has been an explosion of rabbits and chipmunks around here. He would leave trophies on the front step every couple days. Man, I miss that cat!
There's a million kitties out there unloved, no home, gonna get put to sleep or die miserable somehow living out feral. Get a coupla and give them a home. I say a couple, preferably littermates, as they need companionship beyond human contact. Beyond first shots and spaying/neutering, not very expensive to care for either. And very nice little friends. Went for a walk this evening, had seven dogs and four kitties following me around. that's not all my cats, just what went for a walk. They all catch and kill little rodents or rats, too, earn their keep. I give em just enough food to hang around, but not enough to fill em up, that makes them go hunt. Well, little kittens like puppies, need all the food they can eat, but after around six months old or so they will be good enough hunters, even without a momma to show them, so you can start to gradually cut the food down.
Our place when we moved in was simply overrun with rats, no one lived in this cabin for five years. We got cats, now very little rats, just once in awhile do I see one. Used to be they were just running around in dang packs all over, hundreds of them. Don't even have rats in the chicken coop, some of the cats hang out in there, and they have never bothered the chickens at all, oddly enough.
And we got a big black snake lives in the greenhouse, and a smaller one around the wood pile, that helps too.
