The Pros of animal testing is to test a substance on the animal to see the effect similar to human without giving risk to humans. They will input the data so that they will know if the substance is suitable for peoples or not. The Cons of animal testing is animal abuse and cruelty. Lab workers usually obtain stray animals and treat them like how the Nazis treat the Jews. My opinion about animal testing using a household use is very unnecessary. insects such as flies, cockroach, and red ants would be great to replace animal testing.
