I love watching how our cats are similar to big cats. I remember watching a show a long time ago that compared the behavior. It's amazing how similar they are. I remember seeing two tigers in the Bronx Zoo. They have large outdoor enclosures and in the part that house tigers, you ride on top in a monorail and watch them. One tiger was washing itself - just like a regular house cat. The other one was rolling. It was just so funny.
I am even more fascinated with small wildcats. I've been watching many wildcat videos, they are so amazing. The black-footed cat is tiny, and it's so fearless and ferocious. Then, European and Scottish wildcats, they just look like slightly larger tabbies, most of us wouldn't tell the difference, and behave in such a similar way - aside from the fact that they are solitary, and yet they are fiercer and less tameable than tigers.
