What are white domestic rats called? - briefly
White domestic rats are typically referred to as albino rats, a term used for the white‑coated, pink‑eyed laboratory variety. The name also appears as “white lab rat” in scientific and pet‑trade contexts.
What are white domestic rats called? - in detail
White rodents bred for pet or laboratory use and displaying an entirely white coat are commonly referred to as albino rats. The term “albino” denotes the lack of melanin, resulting in pink eyes and a pure white fur. In scientific literature the species is identified as Rattus norvegicus domesticus, with the albino strain designated as “Wistar Albino” or “Sprague‑Dawley Albino” when describing specific laboratory lines.
Pet enthusiasts often label these animals as “White Fancy Rats.” The Fancy Rat community distinguishes them from other color varieties by the same genetic marker (c) that produces albinism. Breeders may also use the shorthand “white lab rat” when discussing animals maintained for research, emphasizing the standardized genetic background of the strain.
Key characteristics of the white domestic variety include:
- Pink or red irises caused by the absence of pigment in the retina.
- Uniform white fur, lacking any markings or patches.
- High visibility of health indicators, making them suitable for experimental observation.
- Common use in behavioral, pharmacological, and toxicology studies due to the extensive genetic documentation of albino lines.
When selecting a white rat for a pet, owners typically consider the “Standard” classification within Fancy Rat shows, which requires a clean white coat, normal body proportions, and no stray coloration. For laboratory purposes, the choice between Wistar, Sprague‑Dawley, or other albino strains depends on the research protocol and genetic consistency required.
