Canida continues her taxidermy projects with a "mouse mouse" it's a computer mouse with an outer mouse covering. I'll repeat her warning: "This project involves taxidermy, dremels, and sometimes graphic pictures of dead animals. While there are no guts in this tutorial, viewer discretion is still advised." If you are offended by this entire idea don't visit the instructables project page, thanks. Link.
