I think animals should be killed humanely. Always. I've killed lots of little critters in a lab setting...all humanely.
But I've also done a lot of dissection of animals from places that took their fur. The first thing you do in a dissection is skin an animal anyhow. I'd rather work on animals than humans any day because you have to be so much more careful with human tissue. You learn more when you can really dig in. I know it sounds gross but it's necessary.
And anyone who says someone studying something medical should just use computer programs or watch videos scares me. I can play oregon trail but that doesn't mean I could probably handle heading out west in a wagon.
Everyone here knows I'm nuts about my dog. He's like a child to me. But I could wear a papillon coat and not feel guilty if they were raised for their fur and killed humanely.
