Satin
Satin rats are fancy rats with a glossy coat effect that makes the fur look brighter and smoother under light. The trait is a coat modifier in Rattus norvegicus domestica, not a separate species or a color on its own. A satin rat may be hooded, berkshire, black, blue, beige, champagne, albino, Himalayan, or another color pattern; the shine changes how those colors are seen. In some lines the coat also feels finer or silkier, though a naturally sleek standard coat can be mistaken for satin without knowledge of the breeding background.
Care does not differ much from that of other coated pet rats. The coat should look clean and reflective, not greasy, scurfy, or patchy, so skin condition and diet still matter. Routine over-bathing can strip oils and dull the coat; clean cage conditions do more for appearance than grooming products. Satin status may be recorded differently by clubs and breeders, and some pet owners simply use the term descriptively. When choosing or breeding a satin rat, temperament, respiratory health, and sound body type should come before the surface shine.
