BLU Rattery

Pet Rat Breeder  | Denver Colorado

Welcome to Blue Heart Rattery! We are a private rattery and do not typically adopt out to the public anymore. We have more demand than we can fill and are now focusing on providing high quality animals to other breeders! We focus on Russian Blue, American Blue, Black, Siamese, Chocolate, and Ragdoll (which is unique to my Rattery alone).

We are the President of the IFRS (International Fancy Rat Society) and breed towards the IFRS show standard. 

Our Rattery is serology tested through Charles River Labs.
