What kind of fur may show poor grooming or ill health in rabbits?

The term "poor coat" specifically refers to a rabbit's fur that appears unkempt, thinning, or in a generally unhealthy state. When a rabbit is suffering from poor health, it often manifests in the condition of its fur. A rabbit's coat can reflect its nutritional status, stress levels, and overall health. For instance, rabbits with insufficient grooming or those that are ill may have a dull, dirty, or matted coat, which is a clear indicator for caregivers that the rabbit may require attention.

While terms like pelage, phenotype, and paunch are relevant in their respective biological contexts, they do not directly pertain to the specific outward appearance of a rabbit's fur in relation to grooming and health status. "Pelage" describes the fur itself but does not indicate the condition or care of it. "Phenotype" refers to the observable physical characteristics resulting from the interaction of genetics and the environment, and it doesn't provide information on fur care or health. "Paunch" typically refers to a portion of a rabbit's digestive system but is unrelated to fur. Thus, "poor coat" directly addresses the concern about grooming and health, making it the most appropriate choice.
