They can sense earthquakes!
Though it's not a proven theory, some believe cats can detect vibrations of the earth through their foot pads.. The pads of a cat's feet are very sensitive, and some cats behave strangely just before an earthquake hits.
They can dream!
Cats prefer to nap, but if they're relaxed enough to enter a deeper sleep, they produce the same brain wave patterns that we do when we dream.
On average, cats spend 2/3 of every day sleeping. That means a nine-year-old cat has been awake for only three years of its life.
Scientists still don't know exactly where purring comes from. Some believe that it originates in the cardiovascular system rather than the throat. When they purr, they're content—usually. However, a deep purr can also indicate pain. If you know your cat well you will be able to tell the difference in his behavior.
But cats aren’t the only animals that purr —squirrels, lemurs, elephants, and even gorillas purr too.
Cats can drink seawater.
Unlike humans, cats have kidneys that can filter out salt and use the water content to hydrate their bodies. But they can’t taste sweet things. Scientists believe that a mutation in a key taste receptor has prevented cats from being able to taste sugar. No cat will ever know the joy of a cupcake.
Cats can hear dolphins. Theoretically
Cats can hear the ultrasonic noises that rodents (and dolphins) make to communicate.
