PLEASE TNR (trap, neuter/spay, return) and please take a moment to build any one of the many types of feral cat outdoor houses that will protect these babies. There are websites everywhere that tell you what to do....look up feral cat houses and TNR..
Maine Coon Cat...they love the snow. Their fur is four types, and one kind grows to the ground in winter. In summer they all fall out, leaving shorter fur again. I have one of these very smart cats. Even catches Hummingbirds, when I'm not around.
