William De Witt Hyde,
Practical Ethics
“ We are tempted to forget this sensitive nature of the animal, and to treat it as a mere thing.—We have a perfect right to sacrifice the pleasure of an animal to the welfare of ourselves. We have no right to sacrifice the welfare of the animal to our capricious feelings. We have no right to neglect an animal from sheer unwillingness to give it the reasonable attention which is necessary to provide it with proper food, proper care, proper shelter, and proper exercise. ”
