RSPCA, campaigning for animal welfare. We aim to prompt political and behavioural change on a range of animal welfare-related issues; to raise awareness for the welfare needs of our nation’s pets and helping pet owners to ensure the welfare needs of their pets are being met; to improve the welfare of as many farm animals as possible, at every stage of their lives; to ensure wild animals are protected from human activity and unnecessary suffering; to reduce the use of animals in experiments and reduce their suffering with a constructive and practical approach.
