Moreover, animals are convenient test subjects since some species have close DNA structures with human beings. Also, I think animals should be used for testing because animals are innumerable, so scientists can perform a large amount of experiments that could have been performed on people, but at a relatively cheaper price, and without endangering any human. However, these tests should be limited to animals that are in abundance, like rats, guinea pigs, cats, and dogs. Endangered animals should not be subject options, so as to not contribute to their extinction.
One important factor to consider is the issue on morality. I do agree that sometimes, animal testing can be cruel. But wouldn't testing new drugs on people be even more cruel?

In my opinion, medical research is a more justifiable death than feeding stomachs or sustaining the fashion industry. With the issue of cruelty at hand, it should be known that scientists care about the welfare of the animals being tested on. The testing is done under strict supervision and the law protects the animals from cruelty and mistreatment, so animal testing doesn't really entail animal
