From YOUCAT, fact 57:
57: How should man treat animals and other fellow creatures?
Man should honor the Creator in other creatures and treat them carefully and responsibly. Man, animals, and plants have the same Creator who called them into being out of love. Therefore a love of animals is profoundly human.
Although man is allowed to use and to eat plants and animals, he is nevertheless not allowed to torture animals or to keep them in inhumane conditions. That contradicts the dignity of creation just as much as exploiting the earth thoughtlessly out of greed.
