Cats are funny critters. My BIL has a mess of barn cats, and within the past 6 weeks there were two separate litters of kittens. Some of the kittens will not stray beyond the barn doors and scurry back inside when someone gets close. Others decided to wander over to the people area to hang out with everybody to the point of climbing up onto laps to take a nap. Even my wife was tempted to bring one home.
My BIL really needs to take them to the vet for shots and snipping, but that will likely not happen.
