Colorado Rat Breeder | Camarattery

Website Updated June.10.2024

We do have babies available!
FYI...Please be aware that breeding season stops in July & August in the USA. Rats loose fertility in hot weather, so babies are scarce during that time. If you are going to adopt, now is the time. Breeding season doesn't really pick up again until the fall when the weather is cooler.

My Harlan Dark Agouti - Now Called Dark Agouti

I got my DA or Harlan Dark Agouti from the Harlan Labs. DA is a Harlan patent. It is not in circulation in the rat community (except my line, which only I have and I have sent it to RRRA and RuBY ratteries) and is very different than the normal Agouti all other ratteries have. DA is many shades darker and affects all other colors differently than regular Agouti. For example the DA Cinnamon is different, the American Blue DA is peacher, and DA Russian Blue is darker, DA Wheaten is darker, DA Silvermane is much darker and richer etc.. It's like nothing you've ever seen before.


Harlan labs is no longer around. But this rat model is. And widely used in most labs. The Harlan portion of the name has dropped and the labs are calling them Dark Agouti now.
