Shadows & Torti’s


They do exist!

Many believe that tortishell rats don’t exist or are extinct. However a few breeders have bred a consistant line, that produces what appears to be torti patterned rats. As of May 2019, I am working on my 5th generation. Each generation is getting better, with patterns visible at the beginning of fur development. 


Shadows which many have found, are linked to torti rats. A shadow rat is best seen in dark colors, the top of the rat will be dark and the belly a silvery color. Many of my shadows now, have brown or salmon pink bellies, depending on the rats base color. There are other colors possibly connected to this gene, including; mock agouti, midnight blue, midnight mink, midnight russian blue, leaden/graphite, steel, charcoal and others. 

Below are some pictures of rats born at GBR. I have also included some informative links from the internet. This page will be updated often.
