Sahih Bukhari Volume 4, Book 56, Hadith Number 689.

Narated By ‘Abdullah bin ‘Umar : Allah’s Apostle said, “A lady was punished because of a cat which she had imprisoned till it died. She entered the (Hell) Fire because of it, for she neither gave it food nor water as she had imprisoned it, nor set it free to eat from the vermin of the earth.”
