Cat Quiz
How much do you know?

Why cat trivia is unusually unreliable

Cat facts circulate better than almost any other category of trivia, and they are checked less. A number gets written into one listicle, the next writer cites that listicle, and within a few years it is repeated on thousands of pages with no primary source anywhere behind it. By the time you meet the claim it looks thoroughly corroborated, because it is — just not by anyone who measured anything.

The clearest example is the one almost every cat quiz asks. "How many bones does a cat have?" The expected answer is 230. The problem is that a cat does not have a fixed number of bones: tail vertebrae vary from roughly 19 to 23 between individuals, and a Manx may have scarcely any tail at all. Any single number is therefore wrong for a large share of cats, which means the question cannot be scored honestly. It is not in this bank.

Three more that were cut for the same reason. "Cats have 24 whiskers" — the sourcing chain runs to pet blogs and stops there. "Each ear has 32 muscles" — a reference on feline anatomy gives 15, and the two figures cannot be reconciled, so neither can be presented as the answer. "Unsinkable Sam survived three sinkings" — historians note that only one rescue is documented in 1941 reports, that photographs show two different cats identified as the same animal, and that the detailed accounts of the Bismarck sinking do not mention the episode at all. A question whose premise is probably apocryphal has no defensible correct answer.

And the most famous of all: "cats always land on their feet." False as stated, and the study usually produced in support of it — the 1987 survey of cats that fell from high-rise windows — has a survivorship problem built into its sampling, because cats that died on impact were never brought to the clinic that collected the data. The righting reflex is real and worth a question; the absolute claim is not.

None of those exclusions made this quiz easier to build. Each one was a ready-made question with a crisp numeric answer. Cutting them is the point.

How the question bank was built

There are 44 questions in the bank, and each one was verified against a named source before inclusion. Shaky claims were cut rather than padded in to hit a round number, so the bank is smaller than it could have been and nothing in it is marked unverified.

The sources are deliberately mixed, because different kinds of claim need different kinds of evidence. Several questions rest on peer-reviewed research: the 2007 Science paper by Driscoll and colleagues on the Near Eastern origin of cat domestication; a 2014 PNAS paper on the earliest evidence for commensal domestication processes; Herbst and colleagues in Current Biology (2023), which found that cat larynges can produce purring frequencies without neural input; the 2020 Scientific Reports study that tested slow-blinking as a communication signal experimentally; a 2019 PLOS ONE randomised controlled trial on whether a hiding box lowers stress in shelter cats; and the 2006 Journal of Nutrition paper establishing that cats lack a functional sweet-taste receptor. Others draw on reference works — the Merck Veterinary Manual, International Cat Care, Guinness World Records for records that are still live.

Two questions are marked contested rather than solid, and the explanation says why. One concerns the top of a cat's hearing range, where studies give 64 kHz and 79 kHz; the octave-scale comparison with human hearing is not in dispute, so the question is asked at that scale. The other concerns a longest-cat measurement whose Guinness record page has since been retired, so the record claim could not be confirmed at source even though the breed and the measurement are consistently reported. Flagging the limitation is better than quietly dropping it or quietly asserting it.

One more piece of housekeeping worth mentioning, because it affects whether a score means anything. The bank originally had zero questions whose answer was the fourth option, and 38 of 44 answered either first or second — a pattern a test-wise player could exploit without knowing a single thing about cats. The options were reordered until the key was spread across all four positions. No answer was changed; only the order of the choices.

What the eight sections cover

Every question belongs to one of eight sections, and the section name is shown above each question as you play, so you always know what kind of ground you are on.

What your score means

Fifteen questions, one point each, converted to a percentage and placed in one of six bands. The bands tile the full range from 0 to 100 with no gaps and no overlap, so there is no score that falls between two of them.

The distribution of difficulty in the bank is roughly 15 easy, 19 medium and 10 hard, which means a confident cat owner who has never read a feline anatomy reference will usually land in the middle bands. That is the expected result, not a failure: the bank includes genetics, registry history and archaeology precisely so that lived experience alone does not top it out. If you want to see where the remaining gaps are, the review screen after your score explains every question in the round — the ones you got right as well as the ones you missed.

The review screen is the part worth staying for. It is also, on the evidence of the pages currently ranking for this topic, the thing nobody else provides: most cat quizzes tell you a number and stop, and a few reveal each answer inline as you go, which spoils their own scoring. Here the answers stay hidden until you submit, and then all fifteen are explained with their sources at once.
