Cats CAN drink seawater in order to survive, though very not so with humans.
True, all animals get a bit of their water intake from food, cats incorporated; but when a cat’s intake of water from all sources is insufficient; their kidneys are resourceful enough to re-hydrate by consuming saltwater. Their remarkable kidneys are able to force out the salt while permitting the potable water to re-hydrate the feline in order to help it survive in times of drought. Cats are an extraordinary animal; special in so many ways.
Most female cats are right pawed whilst males are left pawed; a cat’s brain is more comparable to a human brain than to a dog’s brain; cats can run at an astonishing 31 mph for short distances; and, cats very rarely meow at other cats – only at humans. If humans had eyes/face ration the same as cats, their eyes would be five inch spheres. Only cats can purr and the average cat purrs 10, 950 hours during his/her lifetime. Cats purr at 26 cycles per second, the equal to an idling diesel engine. A cat keeps purring, no matter if it is inhaling or exhaling. A cat has twelve muscles in each ear. Cats have 290 bones in their bodies, and 517 muscles. The typical cat spends 70^ of his/her life sleeping. A falling feline will always right him/her in a clear-cut order. First the head will rotate; next the spine will twist and after that the rear legs will align, finally the cat will arch his/her back to lessen the blow of the landing. Cats are in part color blind. They have the corresponding equivalency of human red/green color blindness. Felines don't see features very well. To them, their human may look obscure when standing in front of them, but they can see up to 120 feet away. Cats cannot see directly under their nose. Their peripheral vision is approximately 285 degrees. Cats possess 473 taste buds, humans have 9,000. Felines can hear 100,000 hertz as opposed to their canine counterpart that is receptive to a range from 35,000 to 40,000 hertz. Compare to cats, humans are completely out of their league with a measly 20,000 hertz.
Maybe that is why we are their staff.
