While I believe all animals should be treated with respect and care, it is unfortunately true that animals will almost always be necessary as a part of trials before medical device and drug approval. Animals play a large role in medical research and there are committees (IACUC) and guidelines in place to ensure ethical treatment in these labs. It sucks, but unfortunately to ensure enough safety before going to human clinical trials, animal trials are necessary. And if you’re sitting here still eating meat, it’s ridiculous to choose to complain about animal testing. I would be willing to bet most animals in a lab setting are treated way more humanely than animals en route to the slaughterhouse.
