More than likely a bobcat. I saw something similar back in October and put a camera on it and it was a bobcat. He would come in, eat, then clean itself, then sleep! All felines will "cache", they kill the animal then cover with leaves to come back and eat on it. Bears will cache as well, but I would bet money this is a bobcat. Let me find those pics
