Our cat has the sweetest disposition and is very social -- among people that is. Bring in an animal and she morphs into "attack cat." It's a bit like watching the Green Hulk transform before your eyes. Our little kitty grows 2 inches taller, and doubles in girth -- or least with her hair all raised, her back arched and her tail up, it seems like it. She starts shrieking like a banshee and charges fearlessly at whatever animal has dared enter her domain.
One time we bought a stuffed dog, a wire-haired fox terrier. This was to be our Asta, a part of my husband's and my Thin Man, Nick and Nora costumes. We set "Asta" on the couch and later when the cat entered the room she caught sight of Asta and, in one flying leap, attacked him with such ferocity we had to laugh. We found it so funny that, I am ashamed to admit, we teased her a few more times by hiding Asta around a corner and watching for our cat to discover him again.
I'm so sorry that I don't have that on video, but here is a video I saw that reminded me of that event. In this You Tube video you see a cat charging an approaching Rottweiler dog being walked on a leash. The dog seems totally taken by surprise and seems to just want to get away. The cat leaps right onto the dog several times before being chased away. The cat seems reluctant to give up the fight and only backs off when others intervene. The dog, meanwhile, seems traumatized and you see him being comforted by his owner. Anyone need an attack cat?
