Perhaps you are thinking of a "Mitten" ferret. This term is sometimes used to describe a ferret with white paws and a white face mask, similar to the markings on a mitten. However, this is not an official breed or classification, and any ferret can have these markings.
Ferret coat colors and patterns are typically described as:
* Color: Sable, black, white, champagne, cinnamon, silver, etc.
* Pattern: Standard, Angora, Albino, etc.
It's important to remember that ferrets come in a wide variety of colors and patterns, and their appearance does not affect their temperament or health.
