We have a squatter in our backyard

Maybe not everybody knows what a squatter is. It's someone who takes up residence on property that is not their own but acts as if it is. Well, we've got a squatter. It would appear that a cousin of Punxatawney Phil has moved into our backyard:

Technically, he appears to have moved into our neighbor's backyard, as he seems to have dug a den under the fence and, apparently, under the storage shed that is just on the other side of the fence:

But I think he likes it here. He appears to be a juvenile groundhog, maybe a year or so old, possibly as much as two. Not very big as groundhogs go, but not from this year's litters, I don't think:

Along with the bunnies, Mrs. Wolves considers him one of her new pets.
