If you’ve ever eaten ice cream too quickly, you know what brain freeze is, when that numbing cold sensation paralyzes your body. Then your love for ice cream compels you to eat some more.
That exact same experience occurred with a cat that got a chance to eat ice cream. The cat likely found the taste of ice cream pleasant, but like humans, learned that eating ice cream too fast can give you brain freeze. If a cat can experience brain freeze, then you know it’s not just humans who can’t think rationally when eating ice cream.
