can you give me a good claim for my essay about Animal testing and the pros and cons

Claim: Animal testing, while controversial, is a necessary evil that has contributed to numerous medical advancements, yet it should be approached ethically to minimize the harm inflicted on animals.

make it 2 paragraphs write it like a 3rd grader would and put pros and cons

Sure! Here's a simpler version written like a 3rd grader:

Paragraph 1:
I believe that animal testing is both good and bad. One good thing about it is that it helps scientists find new medicines and treatments for sick people. They can test these things on animals to make sure they are safe before giving them to humans. Animal testing has helped find cures for diseases like cancer and diabetes, which is really important. But, testing on animals can also hurt them and make them sad. That's the bad part of it.

Paragraph 2:
Animal testing has pros and cons. The pros are that it helps scientists and doctors learn about how medicines work and if they are safe. This helps them make better medicines for people who are sick. Another good thing is that it can help save human lives by finding treatments for diseases. The cons, or bad things, are that animals can suffer and feel pain during testing. This makes them sad and is not nice. Some people think that using animals for testing is not fair and that there should be other ways to do it without hurting animals. So, even though animal testing can be helpful, we need to find ways to do it without causing harm to animals.
