FNRR – Fanratics Rattery 

Fanratics Rattery is a Brazilian hobby rattery located in Mairiporã, São Paulo. My breeding program is dedicated to the responsible and carefully planned breeding of domestic rats, with particular attention to health, longevity, sociability, stable temperament, physical conformation and the long-term development of each line. I maintain detailed records of litters, ancestry and descendants in order to preserve reliable genealogical and health information for future generations. Fanratics is also dedicated to sharing reliable information about the care, nutrition, behavior, welfare and responsible breeding of domestic rats.
