I looked at a recent video of a fox in the backyard, and I thought, damn, our fox got fat. Like, carrying an extra ten pounds of Christmas weight. I almost didn't recognize him.
On further review, though, this appears to be average weight for a red fox (below). I think I've just seen very hungry red foxes so far.
The next night, I saw another fox I didn't even recognize as a fox at all. This guy below is a grey fox.
Gary researched the grey fox and claims it can climb trees like a cat. I don't know how to make that happen.
