For animals that are overworked, underfed, and cruelly treated; for all wistful creatures in captivity that beat their wings against bars; for any that are hunted or lost or deserted or frightened or hungry; for all that must be put to death...and for those who deal with them we ask a heart of compassion and gentle hands and kindly words.
