Animal behaviour and, as a result, animal welfare are increasingly complex areas of study, with the diversity of the animal kingdom and new research findings ensuring there is no one, easy answer. Instead, we need to take a holistic approach, combining scientific principles with both philosophical and ethical considerations to develop all-inclusive policies and legislation that decide how society should interact with domestic, farm and native animals. With a focus on domestic animals, while also referring to wild species to reinforce the arguments, this book:¿ promotes direct observation for those who claim to be interested in animals, their behaviour, and their welfare.¿ considers the concept of consciousness, how it can be assessed, and how it relates to suffering and animal welfare more widely.¿ emphasizes the need to understand better how animals behave both with humans and outside of human influence, considering the diversity of behaviour and sensorial capacities across species.¿
