What notable sign is associated with fur mites?

Visible "walking dandruff" is characterized by the presence of tiny white flakes that can be seen on the skin or fur of the affected rabbit. This occurs because fur mites, particularly Cheyletiella, live on the surface of the skin and feed on debris, leading to a flaky appearance that resembles dandruff. This visible sign is one of the most notable indicators of a fur mite infestation, effectively highlighting the issue in a way that can be easily recognized.

While sudden fur loss, severe itching, and dark crusty lesions may also be associated with various skin conditions or infestations, they are not specifically linked to fur mites as prominently as walking dandruff. Sudden fur loss can be due to other factors such as stress or disease, severe itching may point to other parasites or allergy issues, and dark crusty lesions are often related to bacterial or fungal infections. Understanding these signs helps in correctly identifying and addressing fur mite infestations in rabbits.
