question #1 Sahih al-Bukhari 2365, Book 42, Hadith 13 : What are the consequences of mistreating animals in Islam?

Allah’s Messenger (ﷺ) said, “A woman was tortured and was put in Hell because of a cat which she had kept locked till it died of hunger.” Allah’s Messenger (ﷺ) further said, (Allah knows better) Allah said (to the woman), ‘You neither fed it nor watered when you locked it up, nor did you set it free to eat the vermin of the earth.’ ”
