Without even considering the fact that sewing an animal's eyes shut is horrible, why do they think that finding out what's going on in in the brain when someone can't see is anything to do with having a lazy eye?
Then we have the question of whether or not what happens in a kitten's brain is anything remotely similar to what goes on in a human brain. Probably not.
And THEN there's the problem of how you treat whatever it is they discover. Suppose the ideal 'cure' is aspirin. Well they won't ever know that because ASPIRIN KILLS CATS! Using cats as test subjects is already a blind alley. (Sorry about that. It's not supposed to be a joke.)
Let me say again. Stop testing things on animals because:
- the results you get are NOT relevant to humans
- the methods are NOT the best way, let alone the only way
- there are plenty of cell-based and tissue-based alternatives
- 'just because you'd like to know' isn't a good enough reason to hurt animals
Of course it's not only the scientists who are being silly about this. Some of the people who are against animal testing don't help the cause by being rude, suggesting that the scientists should have nasty things done to them, saying that we should test on criminals and paedophiles. That is just as wrong as the animal testers. Sorry - but it is!
Learn the science, people. Talk to the researchers in terms they understand and respect. Then MAYBE we're in with a chance!
