Perhaps I'm odd, but I choose not to use cosmetics - can't be bothered with make up etc, and have probably saved ?100s over the years. We use the minimum of cleaning products, and choose partly on the basis of animal testing, as well as environmental qualities, although using minimum quantities is often key - eg clothes washing liquid recommendations are usually about twice what is needed.
I eat meat, but choose it carefully eg have eaten culled goose, rabbit etc killed as pests, because if they had to be killed, then their bodies should be used in full. When we killed one of our ducks which turned out to be male, despite assurances "she" was female, we used everything - meat, blood for black puddings, down for refluffing sections of sleeping bags & duvet jackets, larger feathers for teaching at environmental education centre. The ducks in my avatar are currently laying 1 or 2 eggs per day between them, while controlling slug & snail numbers in our veg patch.
I'm also involved in trying to recapture minks in a stream where water vole numbers have declined in recent years. It does seem that mink farmers released minks when farms became uneconomic and blamed animal rights activists, although it's impossible to say which mink today came from which release, not least because they have bred since release.
However, I'm one of thsoe who probably wouldn't be alive if not for Banking & Best's experiments on dogs in 1920s. These days, being a human volunteer in medical research is something I chose to do, as it's more realistic than using animals, plus I can give informed consent. Also, cell culture is a big component in many current research studies, which don't involve whole humans or animals as subjects.
