Noah’s Ark was full of animals that would never willingly sleep side by side. Hooves beside claws. Wings beside teeth. Now put a lion among them and try to relax.
The other creatures could not. Even resting, the lion was powerful enough to terrify everything nearby.
The medieval account says GOD struck the lion with a fever—the first fever on Earth. The heat weakened the great animal, and the panic aboard the Ark finally eased. The king of beasts, the book says, remained feverish from then onward.
Problem solved? Not quite.
Mice began multiplying inside the vessel. They chewed through food and goods, treating the carefully packed stores like an endless banquet. The animals were safer from the lion, but now tiny destroyers were eating their supplies.
And the answer came from the animal everyone had feared.
The lion’s fever rose. Its nose twitched, its chest tightened, and then came a sneeze big enough for an old animal legend.
Out popped a cat.
Small, quick, and made for the Ark’s narrow spaces, it chased the mice into hiding and protected the stores. I had to read that line twice the first time I met it.
That reversal is the whole charm of the story. The lion begins as the danger and ends as the source of help. The cat does not arrive with a roar—just one impossible burst of breath, ready to follow wherever the mice run.
