We have a profound ethical duty to care for animals because they are sentient beings capable of experiencing pain, fear, and pleasure, similar to humans. This moral obligation, often summarized by the Five Freedoms (freedom from hunger, discomfort, pain, distress, and freedom to express normal behavior), dictates that we must minimize suffering and ensure a good quality of life for all creatures under our influence. Domesticated animals rely entirely on us for their well-being, and our compassionate treatment of them reflects our own humanity and moral development. Choosing to act responsibly towards animals, both pets and those in agriculture or research, is a fundamental test of our character and our commitment to a just world.
