On the third morning of the wanderers’ stay in Ulthar, Menes could not find his kitten; and as he sobbed aloud in the market-place certain villagers told him of the old man and his wife, and of sounds heard in the night. And when he heard these things his sobbing gave place to meditation, and finally to prayer. He stretched out his arms toward the sun and prayed in a tongue no villager could understand; though indeed the villagers did not try very hard to understand, since their attention was mostly taken up by the sky and the odd shapes the clouds were assuming. It was very peculiar, but as the little boy uttered his petition there seemed to form overhead the shadowy, nebulous figures of exotic things; of hybrid creatures crowned with horn-flanked discs. Nature is full of such illusions to impress the imaginative.

That night the wanderers left Ulthar, and were never seen again. And the householders were troubled when they noticed that in all the village there was not a cat to be found. From each hearth the familiar cat had vanished; cats large and small, black, grey, striped, yellow, and white. Old Kranon, the burgomaster, swore that the dark folk had taken the cats away in revenge for the killing of Menes’ kitten; and cursed the caravan and the little boy. But Nith, the lean notary, declared that the old cotter and his wife were more likely persons to suspect; for their hatred of cats was notorious and increasingly bold. Still, no one durst complain to the sinister couple; even when little Atal, the innkeeper’s son, vowed that he had at twilight seen all the cats of Ulthar in that accursed yard under the trees, pacing very slowly and solemnly in a circle around the cottage, two abreast, as if in performance of some unheard-of rite of beasts.
