Didn't that guy just link to it on YouTube though?

Oh phew, I thought you were sending in an army of rats to set off all the mines, kinda like the rats in Wanted. This is much better

Jesus Emily Elizabeth, Azula, Vicky AND Daphne are all the same person. Yep, you've pretty much been there for my entire childhood. Thanks for doing such a great job

Edit: looking at the image in the description I see even more familiar characters. Shame I missed the ama :/

Wow, thats a very expensive rat. Glad to hear they're treated so well, they're nice animals

I'm a vegetarian and also have worked in animal labs. Turns out with research for drugs and disease your options are limited to an animal model, a human model or a synthetic model made in a lab. Animals are real organisms but not quite similar to humans. Humans are hard to test anything in because of ethics, especially if it's an unknown drug or new treatment. Then synthetic lab based models aren't living organisms so they might not throw us all the weird curve balls you get in a real organism.

Usually you have to justify use of an animal model and then ensure that your procedure is as humane as possible before you'll be allowed to go ahead with the project.
