Most people who oppose vivisection do so on moral grounds because they object to cruelty. But the case against animal experiments is strongly reinforced by scientific arguments. This is because people and animals are different in the way their bodies work and in their response to drugs and disease.
*******If animal experiments were a valid method of research, people would go to a veterinarian rather than a doctor when they felt ill! In fact, vivisection is an unscientific approach to medicine because of the constant risk of misleading results.

cortisone produces birth defects in mice but not people, whilst thalidomide works the other way around;
morphine calms people but excites cats, goats and horses;
penicillin is highly poisonous to guinea pigs and hamsters;
insulin causes birth defects in animals but not in people;
the antibiotic chloramphenicol produces the blood disease aplastic anaemia in some human patients but it saves animals;
in dogs, the muscle-relaxing drug tubocurarine causes a severe fall in blood pressure but is comparatively safe for people
and doses of aspirin used in human therapeutics are poisonous to cats.

I could go on all day about this. but if you want to be more familiar this side of the argument please check out the (Campaign Against Fraudulent Medical Resarch )
