There was another cat/bear video I saw somewhere in which the cat chased a bear from the back yard.
We've got a big gray male tom in our neighborhood, eats at my house and the neighbors, cat chow or scraps left for him.
Walks around, *on patrol* every night from house to house, sleeps all day, sometimes on my boat cover, LOL.
Probably weighs in at 20-25 pounds, solid muscle.
