[Well-being--intrinsic value--integrity. Developments in the reevaluation of the domesticated animal]

Owing to selective breeding and conditioning to husbandry methods, domestication has resulted in modification of the anatomy, physiology, and behaviour of animals. Nevertheless, domestic animals cannot be regarded and treated as artificial products. Public interest and concern about the welfare of domestic animals has led to the recognition of the intrinsic value of animals and, in extension of this, to the ethical principle of respect for the integrity of animals. The sensibility and acceptance of these principles by those involved in ethical decision-making depends on their fundamental views about humans and the living world. In order to make judgements about the use of, and interference with, animals, it is desirable to clarify these personal views. The principle of respect for the integrity of animals leads to considerations and arguments beyond animal health and welfare. This is shown by three examples: declawing of cats, caesarean section in cattle, and laying hens in battery cages.
