In the captivating realm of rat genetics, the “Havana” variety is a true delight, showcasing the perfect blend of mink with one copy of the red eye dilute gene (aammRr) or emanating from specific American mink (aaamam) lines. This enchanting breed boasts a warm and opulent rich brown coat, creating a tapestry of color that’s simply irresistible. Their eye color, a harmonious mid-ruby hue, beautifully complements their luscious fur. It’s worth noting that while the red eye dilute gene is technically recessive, the magic of the mink background ensures that even with just one copy present, it influences the coat color, making this a special exception. Interestingly, our Havana rats tend to emerge from litters that are generously endowed with red eye dilute, yet despite this, they sometimes exhibit not only the classic ruby eyes but also black, ruby, or even odd eyes, adding an extra layer of fascination to this remarkable breed.
