True or False...there are no purebred rats in the pet world?

Rat species, strains, breeds and types: "Breed

A breed, according to Webster's Dictionary again, is a group of animals presumably related by descent from common ancestors and visibly similar in most characteristics. A more precise definition of breed is found in Desmond Morris' book Dogs: the ultimate dictionary of over 1,000 dog breeds. According to Morris' definition, a breed is a type of animal that differs from all others of the same species in some way, has a separate history and breed name, and has been breeding true for a number of generations. So, beagle and Doberman are examples of different dog breeds.

According to this definition, there are no separate breeds of rats (yet).

A purebred animal (again according to Webster's) refers to a member of a recognized breed, strain or kind without admixture of other blood over many generations.

So, because there are no separate breeds of rats, there are no purebred rats in the pet world. There are, however, many different strains of rats in laboratories, and a rat from one of those strains could conceivably be called purebred. However, 'purebred' is a term that is never used in laboratory rat breeding."
