While we make it a point to only purchase products that were not tested on animals (cruelty free products), I don't think I have ever heard the underlying concepts verbalized quite as effectively as this:

"...using an endangered species to help an overpopulated species become more overpopulated doesn't make rational sense." - Chimpanzee and Human Communication Institute http://www.cwu.edu/~cwuchci/faq.html

If you are interested in high quality, well-packaged, cruelty-free cleaning products, consider Method (http://www.methodhome.com/). We have had a lot of success with them.
