Is cat liquid?
GPT-3.5
GPT-6 Astra
Not literally—cats are solids. But their flexible spines and squishy bodies let them curl up and seem to “flow” into containers, which is why “cats are liquid” is such a great meme. 🐈🫗
What changed
GPT-3.5 answered the question straight and never noticed the joke. Its reply is correct, earnest and a little funny by accident: it defines a liquid as something that can “take on the shape of the container they are in,” which is exactly the observation behind the internet’s cats-in-bowls photos. It then concludes, with total seriousness, that cats “are not actually liquid.”
Astra gives the same verdict, “Not literally,” but recognizes the question as a meme and says so, in a third of the words. It explains why cats seem to flow (“flexible spines and squishy bodies”) and adds a cat and a pouring jar emoji. Neither answer mentions the best possible reply: a physicist won a 2017 Ig Nobel Prize for a playful paper arguing that, on a long enough timescale, cats do behave like liquids. Astra gets the tone right, but both leave the funniest fact on the table.
