National Anti-Vivisection Society
Dedicated to abolishing the exploitation of animals used in research, education and product testing.
Their site is very well laid out and extremely informative: "Credible answers for a cruelty-free world". In a short visit you will learn a lot about animal experiments in science and product testing, and why they are not necessary.
Unable to have charitable status because they are campaigners, they rely entirely upon donations to help them.
