At first glance at the body it does resemble a Mountain Lion but in reality I think you have a large Bobcat here. The ears are the biggest giveaway. Some Mountain Lions will have a faded amount of white on the back of the ears (most don't have any) but definitely not as much white as the cat in your picture. Those are in my opinion 100% Bobcat ears. Also if you look closely you can see a dark black spot in the picture at the rear of the animal. That black spot is in the perfect location to be the black tip of a Bobcat tail. I think you have a big Bobcat here.
