What can the term "definition" often refer to regarding rabbit fur?

The term "definition" in relation to rabbit fur commonly refers to the clarity of color contrasts on the fur. This includes how distinct and well-defined the patterns or markings are in relation to the base color of the rabbit's coat. Clear definition in color means that the boundaries between different colors or patterns are sharp and easily distinguishable, which is often a desirable characteristic in show rabbits. This clarity can influence the overall appearance and appeal of the rabbit, contributing to its evaluation in competitions or exhibitions.

Other choices like density, health condition, and age may affect the overall quality and appearance of the fur but they do not specifically relate to the clarity of color contrasts. Density refers more to how thick the fur is rather than the definition of its colors, and health condition might affect the luster or general appearance but doesn't define the color contrast. The age of the rabbit can also influence fur quality but is not relevant to the aspect of color definition.
