Perhaps we're later ordering Christmas Cards than most but, if you haven't already ordered, perhaps you'd like to consider which charities perform experiments on animals.

Of course we wish to support charity but, in my opinion, animal experimentation (vivisection/laboratory animal experimentation) is not only inhumane, it is also non-productive of medical benefit. In fact, I believe it holds back potential medical advances.

Thankfully, there are plenty of other charities that do not experiment on animals. They get our support.
