Lone Hunter, the incident to which you are referring took place in California. The cat was rabid, and malnourished, and attacked these people without provocation while they were camping. The husband lost most of his thumb holding the cat down, and the wife managed to kill it with a kitchen knife. Believe it or not, animal rights activists were enraged by the courageous action these two people took to preserve their lives.
That said, I can imagine few things more terrifying than being attacked by a big cat. They're fast, strong, and sharp all over. Holy Spirit aside, the gist of the article referenced above is, if you're attacked by a cat, better hope someone with a gun is nearby.
