Varieties We Breed
Here at EVO we specialize in several varieties of rat. Unlike dogs that are identified by Breeds, rats are identified by variety, which is the combination of genes that are expressed (visible). We do not breed every variety of rat, or every color or coat type, we breed the varieties that we find visually appealing to us, or that we enjoy the challenge of producing. Some varieties may be combined, such as Silvermane and Harley, or Harley and Downunder. Most of the varieties we breed come in both Dwarf and Standard sizes.
WerewolfWe have been working with this truly unique gene since 2018. We have a News Post giving more information about Werewolf here.
Thank you to DEMOcrattery in Chicago forgiving us this amazing variety. 
SilvermaneSilvermane rats are incredibly beautiful with their cute masks and stunning silvering. The type and temperament of this line is exceptional. Silvermane coats are known for being especially soft.

Velveteen/RexWe also breed rexoid coat types in some of our lines, mainly Marten and Fawn. Our goal is to produce animals that have soft curly coats that keep defined curls through to adulthood
|
DownUnderDownUnder is where markings are 'mirrored' on the rats belly, so a hooded rat, which normally has a white belly, will have a stripe, and a varigated would have spots. Heres an example of a baby varigated Downunder with belly spots.
Roan/HuskyRoan (sometimes referred to as Husky) rats are a gorgeous combination of a fading gene and facial markings (blaze/headspot). We breed standard coat, Harley, standard ears and Dumbo.

WhitesideWhiteside marking is a band of white across the belly, extending up both sides. The lines should be clean and have a squared appearance. When viewing the underside the rat should appear to be wearing a crop top and PANTS.
Other MarkingsWe also have other markings in some of our lines such as Hooded, Varigated, and Berkshire. Since these are not markings we are actively working towards, they will often appear Mis-Marked (MM).

Black Eyed SiameseWith lineage back to Georgie 2.0 and a beautiful Black Eyed Siamese from Atlantis Rattery, we have developed a stunning line of BE Siamese with full points (self), big expressive eyes, and sweet temperaments.
|
MartenOriginating from Europe where they are referred to as 'Red Eyed Devils', our Martens with red eyes that almost glow from within, were imported by Atlantis Rattery. We breed Red Eyed Black, and Black Eyed Silver Agouti.
|
Pearl, Merle and MinkAlong with Werewolf, DEMOcrattery was generous enough to give us starting stock for a pearl line. Truly beautiful rats, with multi-dimensional coats. While we have not had merle pop up in our lines for some time, it is a variety that we are hoping to secure in the near future.
BlackA good self black is a must-have in any rattery. Breeders use self black to breed out white markings on Siamese rats where it is a fault. Combining Russian and American Blue, and Mink, you can produce some pretty color variations.
|
Agouti, Fawn and CinnamonAgouti rats are far from borning! Our agouti have been combined with Mink to produce Cinnamon, with Ruby Eye Dilute to produce Fawn, and Pink Eye Dilute to produce Silver Fawn - add velveteen for soft wavy curls that show off the banded coat hairs for a truly beautiful rat.
American Blue/Powder BlueOne of our favorite genes is the American Blue/Powder Blue which we acquired back in 2015. American Blue is non-heathered light blue cast. Powder Blue is the same gene but selected for a creamy undercoat.

Dwarf Rats
We have been breeding dwarf since 2015. Dwarf are roughly one third the size of standard size rats, but have HUGE personalities. We breed dwarf sizes in many of our coat types and markings. To find out more about Dwarf Rats check out our blog post that explains more about the gene.
