Neighbor Suzanne Giovanetti first spotted Jack's accomplishment after her husband saw a bear climb a tree on the edge of their northern New Jersey property on Sunday. Giovanetti thought Jack was simply looking up at the bear, but soon realized the much larger animal was afraid of the hissing cat.
It's even more impressive when you look at Jack and realise that he doesn't even have a tail to puff up and be threatening with!
