Cats have ABS Brakes
Cats have a sixth “finger” (called a carpal pad) on the inside of the wrists of the front paws. It’s also found on the paws of big cats. It is not believed to have a function in normal walking, but is thought to be an anti-skidding device used while jumping (or perhaps during a raucous game of Thundering Herd of Elephants).
Exactly how many lives do they have?
Not all countries believe that cats have nine lives. In some Spanish-speaking regions, cats are believed to have seven lives. The number drops to six in Turkey and Arabia.
No hot flashes
Cats are descended from desert cats and as a result can tolerate high temperatures well. Despite their furry coats they show no discomfort until their skin temp rises above about 126 °F. (Humans start to feel uncomfortable when their skins temp exceeds 112 °F — except for menopausal women, who sweat anytime the ambient temperature rises above 24 °F.)
I kidney you not
Cats’ kidneys are so efficient that cats can survive on a diet consisting only of meat, with no additional water, and can even rehydrate by drinking seawater.
Cats don’t have a lot of taste.
The cat’s taste buds only respond to amino acids, bitter tastes and acids. They have only 473 taste buds compared to 9,000 for humans.
Which came first — the whisker or the blink?
Of course, you know that cats have dozens of whiskers all over their bodies — not just on their faces — to help with navigation in the dark. But did you know that their whiskers trigger protective blink reflexes to protect the eyes from damage?
Ferals don’t have much to say
Domestic cats use many vocalizations for communication, including purring, trilling, hissing, growling, snarling and several different forms of meowing. In fact, some have extensive vocabularies. In contrast, feral cats are generally silent.
The female cat’s heat periods occur about every two weeks and last 4 to 7 days.
Those barbs on the cat’s tongue that makes it feel like sandpaper are called papillae and contain keratin, a type of protein found in hair and nails.
And you thought 20-yr-olds were geezers
The oldest known cat, Creme Puff, died at a verified age of 38. Females cats, on average, live a year or two longer than males.
The better to see you with, my dear…
The domestic cat’s pupils are much larger, relative to their eyes, than the pupils of the big cats.
And yet, their necks are so short…
Among mammals, the cat has a rare gait called a pacing gait, in which they move the two legs on one side of the body before the legs on the other side. This gait is also employed by camels and giraffes.
Seven percent of cats snore.
