The one we had was a stray semi-feral. She believed in love, affection, and the extermination of all other cats. She weighed seven pounds soaking wet and would attack any cat she saw. She started her relationships with dogs by walking up and slashing their faces. In the twelve years we had her, she only backed down once. We had an ancient german shepard/husky who had had enough of her attacks. When she got up hissing in his face he bared his teeth and let out the deepest growl. She was a few inches from his fangs. The expression on her face was great...I'm going to kick your ass...ooh...those are really big teeth!...hmmm...I think I'll just to go over there now...<slink away>.
Edit: Long hair, oh yeah, think hairballs and matted fur. Cutting mats out of a shreiking chainsaw isn't much fun nor is shooting catlax down its throat. Mats are like dreadlocks on steroids.
