how can anybody be so cruel as to test on animals and not feel anything?!!!

its kinda ez to figure out. its all about the money, they dont care its all about the money

How do آپ know that they don't feel anything? It is a necessary evil unfortunately...and maybe there are actually people in research that realize this and want to make sure that these animals get the best care possible.

I don't know on a personal level, but sometimes a job is a job. People need an income, they need money, jobs can be hard to find so when you're getting paid for something...morals can go out the window easily.

Money, on a technical level but on a personal level, they're SOB's.

Much medical research could not have proceeded without animal testing. It's not universally bad.
