EXPERIMENTS on animals are indefensible as they lack any scientific reliability in regard to humans.

Animals suffer different diseases to us and artificial diseases induced in them are not the same as suffered by people in real life.

No independent observer, RSPCA representative, police or MP has the right of entry into a laboratory to witness an experiment.

They are shrouded in secrecy.
