![]() You will not have a half dumbo or half rex rat. If you breed two varieties of rats you never get a mixed variety. Our pet rats belong to the species Rattus norvegicus, commonly called the Brown rat or Norway rat, specifically Rattus Norvegicus Domestica, to show they are domesticated pet rats.Ī breed would refer to much grander differences that actually affect the nature, personality, instincts, drive, etc… of the animal. Now the Genus- Rattus: rats! But that includes a ton of different types of rats that vary greatly in some cases.Īnd we finally have Species-R. Then we have the Family- Muridae: “a very large family of relatively small rodents (superfamily Muroidea) that include various originally Old World rodents (as the house mouse and the common rats) that are now cosmopolitan in distribution and that in recent classifications often include the cricetid rodents as a subfamily (Cricetinae)” Next is the Order- Rodentia ( Rodents): “any of an order (Rodentia) of relatively small gnawing mammals (such as a mouse, squirrel, or beaver) that have in both jaws a single pair of incisors with a chisel-shaped edge” Smart science people classify animals into different groups, based on things they have in common and how they are related.įirst let's discuss the class- Mammalia ( Mammals): “a warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, the secretion of milk by females for the nourishment of the young, and (typically) the birth of live young.” Or with some colors you may have them just not be all that ideal such as with rusting. On top of that, many rats are unlikely to be bred to show standards and could be called mismarked that doesn't really fit with the exact standard. I prefer and use The American Fancy Rat and Mouse Association (AFRMA) standards. It is also important to note that different countries and clubs give different names to certain varieties. If you looked at the rat you would say it is albino but it is actually Siamese. This would mean that the Siamese would not show any points and be all white. A wedge blaze is a white triangle covering their nose and between the eyes. ![]() For example, I have a Marked Wedge Blaze Siamese. There is a difference in phenotype vs genotype. It is important to note that sometimes simply knowing their color/markings won't always give you what variety they actually are without knowing their pedigree/history. So I will just give an explanation on what it all means! There are lots of great sources out there already that explain & show pictures of the different varieties. ![]()
