Nine Lives, or Seven?
Depending on where you grew up, a cat has nine lives or seven. Both are old, both are confident, and nobody actually knows where either came from.
Ask an English speaker how many lives a cat has and you will get nine. Ask in Madrid, Rome, Berlin, Athens, Istanbul or São Paulo and you will get seven — siete vidas, sette vite, sieben Leben. Parts of the Arabic-speaking world also say seven. A few traditions say six.
Everyone says it with total confidence. Almost nobody can tell you why.
The English nine is genuinely old
It is attested well before anyone thought to write it down as folklore. Reginald Scot, arguing in 1584 that witchcraft accusations were nonsense, mentions in passing the belief that a witch could take a cat’s body nine times. A decade or so later Shakespeare has Mercutio taunt Tybalt as the "good king of cats" and demand one of his nine lives — a line that only works as a joke if the audience already knows the count.
So by the late sixteenth century the number was common currency in England. Where it came from before that is the part the internet will confidently fill in for you, and should not.
The explanations you will be offered
Nine is three times three, and three is a sacred number — so nine is a "trinity of trinities". This is the most repeated explanation and has no evidence behind it beyond the arithmetic being correct.
The Egyptian sun god Atum-Ra was said to contain nine deities and sometimes took feline form. Appealing, and a very long way from sixteenth-century England with nothing joining the two.
Cats are hard to kill — they right themselves in mid-air, survive falls, disappear for a week and stroll back in. The number is arbitrary; the observation behind it is not.
That last one is the only explanation that does not require a chain of assumptions. It also does not explain why the number differs by language, which is the genuinely interesting part.
The pattern that actually holds
Nine and seven are both numbers that carry unusual cultural weight in the traditions that use them. Seven runs deep through Mediterranean and Islamic number symbolism; nine has its own long history in English and Greek-influenced usage. The count seems to follow whichever number a culture already treats as significant, attached to an animal that visibly survives things it should not.
The belief is not really about the number. It is about the observation that a cat you were sure was finished turns up on the wall the next morning, entirely unbothered.
The part that is not folklore
Cats do survive falls at rates that surprise people, helped by a righting reflex, a low terminal velocity for their body mass, and a habit of spreading out to increase drag. Veterinary papers on the subject have described a counterintuitive pattern in which injuries do not simply worsen with height beyond a certain point — though the data come from cats brought to clinics, which by definition excludes the ones that did not survive to be brought in.
None of which makes falls safe. High-rise syndrome is a real and common presentation, and the fix is unglamorous: screen your windows and balconies.
The honest answer to how many lives a cat has, then: one. Defended by better reflexes than ours, and by a folk tradition that could not agree on a number.
