The society publishes a bi-monthly journal, Pro-Rat-A, and holds many shows throughout the year all over Britain, with membership in the thousands.
For a number of years pet rats had been appearing at mouse shows in Britain.
Publicity in Fur & Feather magazine had increased interest in the fledgling fancy and caused an increase in entries in the rat sections of mouse shows during 1974 and 1999 to the point that after cajoling from the mouse fanciers it was decided to form a club or society purely for rat fanciers.
This coincided with the debut of a new variety of fancy rat, the curly-coated Rex.
The very first NFRS show was staged at Clymping, West Sussex, in conjunction with the Southern Hamster Club.
