The question is not, "Can they reason?" nor, "Can they talk?" but rather, "Can they suffer?"
Did you know that over a hundred million animals get injured or die due to animal testing? But when you think about is it actually legal? So the thing is it doesn’t matter what we think because there are people who want themselves to live a better life then the animals and they do experimentation on the animals just so humans can live a better life. And there are a lot of animals who die due to suffering in laboratories across the world, apparently it’s legal and people seem to not care about it. Some people say animals aren’t equal to humans and some say they are, so who to believe? But it still doesn’t give us the right to torture animals and let them suffer for the rest of their lives and who knows how long they have until they live. Also is some cases when they are not successful they kill the animals just so we can wear or buy new clothes made by those poor animals. So it is for sure that animal testing is wrong and not effective on some animals. People should be against animal testing because it is an issue of animal cruelty, it is also selfishness, since it makes animals suffer and it is a violation towards animal rights.
Animal testing is bad because it deals with the issue of animal cruelty. It is often argued that these tests cause a lot of pain to the animals and the condition in which they are held captive for experimentation is not at all safe nor healthy for the animals. It also causes animals suffer for the rest of their lives and then they die. This means that afterwards animals aren’t any more active in doing their own things because all of them get locked and stay in cold, barren cages in laboratories and so therefore they can do nothing. But on the other hand there are some people who say testing animals is a good idea because both animals and humans benefit for animals getting experimented
