That would be a Mountian lion/ Cougar, where was that pic taken? To big to be a bobcat, and the tail is to long and the head is to rounded to be a bobcat..A bob cats ears are more pointed and a cougar they are more rounded... The first pic is a bobcat and the second is a Mt lion also notice the fur a cougars fur is more sleak and the bobcats is moer fluffy, Deffently a Mt.lion
