I've had the cats for about 7 years now. Me and my ex-girlfriend were living together for 2 years and recently split-up. I've been on my own for about a month now, but my ex didn't care for the cats and wasn't very affectionate towards them, so I don't thing "she" is a factor in this. Nothing like this has ever happened before. In fact, we were sitting next to each other at the computer when the cat attacked her from behind. What a scene it was!
