3. If you live alone with your cat, beware — if you die in your apartment alone, your cat will probably try to eat you.

5. Cats don't just purr when they're happy — they also purr to signal stress and fear. But the coolest thing? Cats may purr to help regenerate their bones. The purring frequency — 26 Hertz — apparently aides in tissue regeneration and can help stimulate the repair of weak and brittle bones.
6. Speaking of, no one REALLY KNOWS exactly how cats purr. Scientists know it involves the larynx and diaphragm muscles but they're not sure exactly how those muscles work together to create such a cool sensation. SO MYSTERIOUS!

9. There's a cat that lives at a nursing home in Rhode Island who's "predicted" the death of more than 25 patients there. Nurses at the nursing home noticed that the cat, named Oscar, tends to show a ton of affection and care to people who are on the verge of dying — and there's actually some scientific basis for the cat's weird skill. Apparently a dying body gives off a scent that cats are particularly sensitive to.
10. Declawing a cat is actually akin to amputating a limb. "To declaw a cat," explain veterinarians, "you amputate each toe at the first knuckle, taking off bone along with tendons and the claw." Which is why some states — including New York — have considered outlawing it.
