Fancy Rat

🌍 Overview

Fancy rats are the domesticated form of the wild brown rat, bred for temperament and color since Victorian England, most famously by Jack Black, Queen Victoria's official rat catcher, who caught and bred unusually colored rats and sold them to the wealthy as pets in the 1800s. The Rat Fancy became a formal hobby by 1901, and it produced a genuinely different animal from the wild rats it descends from. Fancy rats are widely considered among the most intelligent commonly kept small pets: they learn tricks, respond to their own names, and navigate mazes readily, which is also why wild-type rats have been the standard animal for spatial-learning research in psychology and neuroscience for more than a century. They're deeply social and bond closely with a consistent handler, though their reputation still suffers by association with the wild rats they were bred from.

📜 History

The laboratory line and the pet line separated early. Henry Donaldson took four pairs of albino rats with him to the Wistar Institute in Philadelphia, where from 1906 he and Helen Dean King bred them toward a standardized research animal, and in 1912 the institute began shipping rats to other laboratories; most modern laboratory strains descend from that colony. The pet side nearly lapsed instead. British shows dropped rat classes for decades before they returned in 1968 at the London and Southern Counties Mouse Club, and the National Fancy Rat Society formed on January 13, 1976, staging its first exhibition at the Bradford Championship Show a week later.
