Also, I just have to ask, what rabbits are on tropical islands
Maybe the British left some there in the 1800's? We did that a lot
I'm writing a persuasive essay on animal testing

I had a friend who studied Biology and was a passionate animal rights protester. Think about it - how similar is a human to a rat? Apparently, most animal testing is inconclusive, and is routinely confirmed on human subjects anyway. Even primates do not always react in the same way as humans

You could check out some of the anti-vivisection sites? They have photos of cats and dogs being tested on, you could show your class? Like:
http://www.bava.org.uk/ (BAVA were involved in the protests against Huntingdon Life Sciences over here, who are Europe's largest contract testing laboratory) Some of the site's quite strongly worded, and some of the activists got a bit extreme and started (allegedly) intimidating shareholders. I wouldn't want to advocate that sort of thing

Well, you can see what you think...
There is a lab in the US who are cultivating human tissue for donor parts. They collect boys' foreskins that have been removed during circumcision, and try to grow lungs, kidneys, heart valves etc. They have so far been successful in cultivating skin. So why not test drugs and cosmetics on cultivated organs instead of animals?

It is a thought for the future, perhaps...
