The chemicals that are used in science experiments or makeup testing intoxicate their immune systems, and no matter what animal it may be, they will still suffer by being forced to take medications down their throat, harmful substances on their skin or their eyes, plus painful procedures. Almost all of the time the animals are killed after the tests either by injections or decapitation. According to PETA, a non-profit organization that supports the ban of animal testing throughout the world, over 100 million animals including monkeys, rabbits, cats, dogs, fish, birds, mice, rats, and so on. 97% of said animals are killed directly after the experiment concludes. The failure rate of these tests is about 95%, meaning that billions of dollars are put towards meaningless experiments that harm the animals every year for no reason at the same time.
