Islam teaches Muslims to treat cats well and that the cat is a creature to be cherished and loved..

"Those who are kind and considerate to Allah's creatures, Allah bestows His kindness and affection on them. Show kindness to the creatures on the earth so that Allah may be kind to you." Hadith - Abu Dawud and Tirmidhi

Allah's Apostle 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 Apostle 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 insects of the earth.' " Hadith - Bukhari 3:553, Narrated 'Abdullah bin 'Umar [Also in Muslim, Narrated Abu Huraira]
