My Sahara does this mauling thing just like your B. Why do they go for the throat, Sahara does this to my small 17 yr. old cat. I had to get a home electronic trainer device to get her off of my cat. One day she dragged her across the carpet by her collar, and she was yelling like Sahara was killing her. Guess what, since I got this device she has stopped, thank God. Now all I have to do is push the sound button as she runs, don't have to shock her, she knows if that doesn't work the shock comes next. Your B is so cute in the top pic by the title of your post.
