What is the main concept behind animal welfare?

The focus of animal welfare encompasses not only the basic needs of animals, such as shelter and food, but also their emotional and psychological state. This means that to ensure true animal welfare, it is crucial to consider both the physical health of animals and their mental and emotional well-being. Ensuring the psychological well-being involves allowing animals to express natural behaviors, reducing stress, and providing enrichment in their environments.

While providing basic shelter and food is fundamental, it does not fully encapsulate the broader and more comprehensive approach that the main concept of animal welfare entails. Similarly, managing animal reproduction and restricting human interaction with animals do not align with the holistic view that prioritizes a balanced state of physical, emotional, and psychological health for animals. Therefore, the correct answer captures the essence of what constitutes the overall welfare of animals.
