Calling all curious cats! Whether you have a cat, are considering adopting a cat, or just love cats, we rounded up the most interesting cat facts we could find to help you better understand these adorable creatures.
5. The richest cat in the world inherited $12.5 million when its owner passed away.
According to the Guinness World Records, Blackie the cat inherited £7-million ($12.5-million) when his owner Ben Rea died in 1988. The millionaire antique dealer refused to recognize his family in his will so most of the fortune was split between cat charities.
6. Purring actually improves bone density and promotes healing within a cat. The purring frequency — 26 Hertz — apparently aides in tissue regeneration and can help stimulate the repair of weak and brittle bones.
9. Adult cats don’t release any particular key hormones during sleep. They just snooze all day because they can.
The fact that cats don't have duvets is only of small comfort here.
10. Of all its senses, a cat's strongest is its hearing. They hear about four times as well as a human.
13. Cats can change their meow depending on the situation, such as when they're demanding to be fed.
15. Cats cover their waste in sand or litter as a sign of subservience to humans. If they don't cover up their waste, it's like they're saying, "I'm not afraid of you, human."
20. Black cats may be a bad omen in the US, but in other countries, such as England and Japan, they're a sign of good luck.
21. Cats can drink seawater.
Unlike humans, cats have kidneys that can filter out salt and use the water content to hydrate their bodies. (Yes, I know seawater doesn't come out of the toilet.)
23. The furry tufts on the inside of cats’ ears are called “ear furnishings.”
They insulate the ear, and help filter out direct sounds and debris.
24. Cats can hear dolphins. Theoretically.
Cats can hear the ultrasonic noises that rodents (and dolphins) make to communicate.
25. Cats can’t see directly below their noses. That’s why they miss food that’s right in front of them.
28. But cats don't just purr when they're content, they also purr when they're under duress, or when they're injured.
34. Cats' homing instinct may be due to magnets in their BRAINS.
Cats find their way home through a process called "psi-travelling" — experts think they navigate via the angle of sunlight, or that they have magnetised brain cells that act like compasses.
36. Cats may have evolved their “tone of voice” to communicate with humans.
Cats' natural vocal range would be inaudible to humans, but they communicate feelings such as affection, hunger, and fear within the range of human hearing. Some researchers believe that this is learned behaviour to help cats to relate to humans.
37. The more you talk to your cat, the more it will talk to you.
If you chat to your cat, it will increasingly chirrup and meow at you.

46. Cats have approximately 32 ear muscles.
47. Your average house cat's genetic roots can be found in the Middle East. In a 2007 study, researchers found that house cats shared the majority of their DNA with wildcats found in Israel, the United Arab Emirates, Bahrain, and Saudi Arabia.
48. If you live alone with your cat, beware — if you die in your apartment alone, your cat will probably try to eat you. According to NYC medical examiner Judy Melinek, in her book, Working Stiff, "Your faithful golden retriever might sit next to your dead body for days, starving, but the tabby won’t. Your pet cat will eat you right away, with no qualms at all. I’ve seen the result.”
49. There's a cat that actually has a master's degree! His name is Colby Nolan, and his name was used in an investigation into bogus degree-granting practices at Trinity Southern University and several other universities in 2004.
Colby was granted an MBA after the university claimed that cat had a 3.5 GPA. Impressive.
51. 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.
52. 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.
54. 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."
This is why certain states — including New York — have outlawed it.
55. It was considered a capital offense to kill a cat in ancient Egypt.

61. Cats may be able to detect earthquake tremors 10 or 15 minutes before humans can.
Although no one knows for sure, theories suggest that animals — like domestic cats — can feel the Earth vibrate before humans can. There have been other theories that say they can sense electrical changes in the air or gas released from the Earth.
62. There's an orange tabby named Stubbs who's been the mayor of the town of Talkeetna, Alaska for the past 20 years.

65. Have you ever noticed your cat going crazy for olives? That's because olives have a similar chemical compound in them to catnip.
66. Is your cat ignoring you on purpose? Probably. A Japanese study found that cats are actually capable of recognizing their owners' voices — they just actively choose to ignore what the owner is saying.

68. A cat’s heart beats nearly twice as fast as a human's heart.

73. Cats don't have collarbones, meaning they can fit through openings as small as their heads.
74. The Hermitage Museum in St. Petersburg, Russia, "employs" 70 stray cats that are tasked with controlling the mice population and preventing them from chewing on the artwork. The cats even have their own "Press Secretary to the Cats" (unofficial position, but you know).

87. It turns out cats aren't exactly nocturnal. They're considered "crepuscular," which means they typically have a schedule where they're most active at the same dawn and dusk hours. Often those hours don't correspond with YOUR favorite waking hours (does your cat ALSO like to wake up at 5 a.m.? It's pretty great, right?)
88. Similarly, cats crave cardboard boxes because the box keeps them warm and reminds them of the small crevices and hiding spots they might have crept into in the wild.
89. Fur color changes in Siamese kittens depends on their body temperature.
90. Ever notice that your cat runs around a bunch after using the litter box? That's because they're instinctually trying to confuse potential predators who smell their poop.
