Hubbys cat went after a man that forced his way into our home when I was 8 months pregnant and couldn’t run to save my life. The man fled.
Yay, Kitty!
I once visited a house in Philly on business (it was a rowhouse) and the next-door neighbor had a cat leashed to the stair handrail on the front porch. This thing was hissing and growling and stretching that leash like a rabid Doberman, trying to get at me. It was an attack cat! - - Never saw anything like it. Freaky scary.
