What do companies do to the animals when testing them?

Pharmaceutical companies force feed or pump drugs into the stomachs of animals to test for side effects and toxicity levels. These tests are typically conducted on rats, mice, and non human primates. Cosmetic and heigeine companies typically put their products in the eyes, nose, ears, and mouths of animals to test the reaction. These tests are usually conducted on small mammals including rabbits. Typically, once certain tests are completed the animals are cut open while still living to reveal the effects on the animal's anatomy. Other experiments deal with electric shocks in order to discourage certain behavior. Also, trauma experiments used to train field surgeons deal with the shooting, stabbing, burning, or abuse of live animals including dogs, cats, pigs and goats.
