Working with dwarf in Russian blue, Russian beige, Pearl, and Pearl merle. 

​

We do not offer rats to the public.

​

We strive to breed our rats to a high standard, working with only one to two lines. We are excited to have our old Russian Blue line back.​

​

Due to our previous lab no longer allowing private breeders to test through them we have made the decision to be a closed rattery. We are unable to guarantee an absences of pathogens* in our animals and feel that it is not ethical to adopt out any rats without that knowledge.

​

*Most pathogens in rats are not harmful to a healthy adult immune system.
