Animals should absolutely NOT be used for testing things! They have feelings just like us, they don't deserve to be treated like this. Killing animals after being used for tests or letting them die being used for tests, it's not fair to them.How would you feel if something that you had never seen before was shoved down your throat or rubbed on your skin? What did they do to us? We should do the tests on the people in jail instead of innocent animals. That or on people who wouldn't mind being used for tests.
