A pregnant cat gave birth to some kittens in my grandfather's garage. (Specifically, the attic of the garage.) We speculate that this was actually two separate litters of kittens because there were actually nine kittens but three died when they fell from the attic. That is actually how we discovered that the cat had gotten into the garage.
I found the three dead kittens and heard some light mewing. After investigating, we took the whole family in and began socializing the lot. My grandfather took very well to being a kitty handler / jungle gym. He would sit in his chair with a herd of kittens running over him.
All kitties pictured found happy homes. :)
