Fancy Mouse

🌍 Overview

The fancy mouse is a domesticated form of the house mouse, bred for coat color and pattern since at least Victorian England, where Walter Maxey founded the National Mouse Club in 1895 and designed the standard show cage still used today. House mice have lived alongside humans for roughly 11,000 years, since the earliest agricultural settlements of the Near East, and the western subspecies Mus musculus domesticus that most fancy and laboratory mice descend from spread from there across North Africa and Europe. Mice are smaller, faster, and considerably more skittish than fancy rats, and most keepers find them harder to hand-tame to the same degree. Their most practical downside as a pet is odor: male mouse urine contains trimethylamine, a compound that gives it a distinctly pungent smell largely absent in rat urine, so a mouse cage needs more frequent cleaning than a same-sized rat setup.

📜 History

Abbie Lathrop moved to Granby, Massachusetts in 1900, failed at poultry farming and turned to breeding mice, starting with a pair of waltzing mice. In 1902 the Harvard geneticist William Ernest Castle placed an order with her, the first time her animals went into a laboratory for genetic work, and her operation eventually held over 10,000 mice in straw-filled wooden boxes. From 1910 she investigated tumors in her own stock alongside the pathologist Leo Loeb, and between 1913 and 1919 the pair published ten papers connecting particular mouse lines to inherited cancer. Clarence Cook Little built his dba strain from her animals, which is how a hobby breeder's barn became the source of modern laboratory mice.
