Bobcat for sure - and a nice one at that. Bobcats can grow to nearly 40 pounds, which is much bigger than your garden variety housecat. Their summer coat is more sleek, whereas the winter coat is shaggier. The tufts on his ears and the bobtail are a dead giveaway.

The camera shot silhouettes the cat, and makes it hard to see his markings. If you'd see him in a better light, you'd see those dark stripes/spots.
