Angry cats have been referred to as ‘the furry buzzsaw’ by many, many commentators. Their combat tactics are completely different than their hunting tactics - a fighting cat will typically try to trip or knock over a larger opponent, then blind it by strikes to the eyes, *then* go to rip out the major blood vessels around the neck.
Yeah, little Fluffy snoozing on the couch is not to be underestimated. The cat is a ridiculously efficient killing machine if pressed.
Cats, as I have always maintained, are the ultimate fighters of the animal world. The “Sugar Ray Robinsons of the the animal world” if you will...
Wow, you have just described the fight between my mother’s 7 pound cat and the Doberman who tried to get her. Cat jumped on the head, gouged out the eyes with hind feet while ripping the jugular with her teeth.
Those which tried too hard to throw her off would generally get the claws dug deeper into the back of their neck or even their eyes. As you said, the cat was no match for the dog's strength. But the dog was no match for the cat's agility.
