There was an old cat who was too feeble to hunt mice as she once did. "I'll need to use a trick!" she thought, so she rolled herself back and forth in the flour until she was completely white all over.
Then she lay there, motionless, waiting for the mice.
The cat thus caught all the mice who were young and foolish.
Then an old mouse approached the flour. He had escaped many mousetraps, and he saw the cat lurking in the flour.
"Some mice don't know any better," he said. "But you can't fool me! I'd know you anywhere!"
Inspired by: Mille Fabulae et Una, a collection of Latin fables that I've edited, free to read online. I am not translating the Latin here; instead, I am just telling a 100-word version of the fable.
Notes: This is fable 195 in the book, which is Perry 511.
