The Prophet of Islam was once performing ablution (Wudhu) for prayers from a pot of water. A cat passed there and turned its eyes at the pot of water with a thirsty look. The Prophet realised at once that the cat was very thirsty, so he stopped the ablution (Wudhu) and placed the pot before the cat. Only after the cat had fully quenched its thirst, did the Prophet resume the ablution (Wudhu).
