I would try petting anything before the minute mark.
Feline Size Comparison: Lions And Tigers And Housecats, Oh My!

Because a moving picture is worth at least 100,000 words, this is a video comparing the sizes of various felines, from the 14″ rusty spotted cat, to the 13.4′ extinct Ngandong tiger. The felines really start looking unfriendly around the 1:10 mark. Of course size doesn’t always matter, and my cats are far more ferocious than you’d expect the little furballs to be. “Thank God they aren’t any bigger,” I regularly tell myself while making sure the bedroom door is closed and locked and there’s a chair in front of it before going to sleep at night.
