This beautiful cat is a serval cat. If you haven't heard of them before, they are BIG. And if you breed a serval cat with a domestic house cat, you get what they call a savannah cat. (More info here for servals and savannahs.)
Aside from being gorgeous, they also apparently like to jump... Count down with us, Cuteheads: 10... 9...8...7... Watch out, cameraman!
