Animal Experiments

Each year inside British laboratories, around 3 million animals are experimented on. Every 8 seconds, one animal dies.


Each year inside British laboratories, around 3 million animals are experimented on. Every 8 seconds, one animal dies. Cats, dogs, rats, mice, guinea pigs, rabbits, monkeys and other animals are used to test new products, to study human disease and in the development of new drugs. They are even used in warfare experiments. Animal Aid opposes animal experiments on both moral and scientific grounds. Animals are not laboratory tools. They are sentient creatures capable of experiencing pain, fear, loneliness, frustration and sadness.

To imprison animals and deny them their freedom to express natural instincts and to deliberately inflict physical pain in the name of science is unacceptable. All the more so because the experiments are bad science in the first place: they do not produce information that can be reliably applied to people. Ending animal experiments will benefit people as well as animals.

The Case Against Animal Experiments



The scientific case against animal experiments is now being voiced in leading scientific journals. In an era of evidence-based medicine and of powerful new analytical tools including high powered computers and robotics, the fatal weaknesses of the ‘animal model’ are becoming more widely known.

The Suffering of GM Mice

Science Corrupted


A major and neglected aspect of the debate over animal experiments are the millions of genetically modified (GM) mice who suffer every year in crude, medically-useless experiments. For every GM mouse used in a ‘procedure’, hundreds more die or are killed as ‘surplus’ or ‘failures’. Not only does breeding and experimenting on GM mice cause terrible suffering, it is also failing to produce cures for people.

Humane Research

copywrite Dr Hadwen Trust


Hundreds of thousands of animals are bred and killed every year so that their body parts can be used in test tube studies. At the same time, huge amounts of a genuinely useful research material – human tissue – is being incinerated. Since 1991, Animal Aid has fought this nonsensical situation.
