2 million of the total 2.88 million procedures carried out on animals in 2020 used mice – that’s over 70%.

In our free guide, we explain why mice are so widely used in research and how we should go about replacing them with more human-relevant, non-animal alternatives.

Over the past century, mice have been widely used in all aspects of scientific research and are the most used species in regulated animal research today.

Mice are a popular laboratory animal for several reasons:

• They are small and relatively easy and inexpensive to keep in a laboratory setting.
• They have a short lifespan so results can be seen quickly.
• They can be easily bred to see side effects on offspring.
• Modern technology allows scientists to manipulate or alter mouse genetics to create new research strains quickly and easily.
• Mice are mammals and therefore share similar genes and physiology to us.

But we don’t believe that the future of scientific research involves mice. We’re working towards a brighter future for animals and humans, where no animal suffers for science.

In this guide, we explain some of the key issues surrounding the use of mice in scientific and medical research and why Replacing Animal Research believes there is a better way forward.
