Slate
Slate describes a grey Mongolian gerbil color variety with a cool, stone-like tone. Some are solid grey, while others carry pied or spotted white markings that break up the coat on the face, neck, body, or tail. The name is used by fancy breeders and pet listings, but it is not a separate species or a radically different type of gerbil. Depending on the line, slate can be confused with other grey or blue-based colors, especially in juveniles or animals photographed under warm lighting.
A slate gerbil is kept like any other Mongolian gerbil. Deep bedding is important because digging and tunnel building are normal behavior, and wood, cardboard, or hay help wear teeth that grow continuously. Most do best with a familiar same-sex companion; sudden introductions can lead to fighting, so rescues and breeders usually manage pairings carefully. Coat color should not be used as a shortcut for judging health. Good body condition, clear breathing, an intact tail tuft, and calm handling history tell a buyer or adopter much more than the label on the color.
