Walking Dandruff in cats is characterized by a moving white substance that resembles typical dandruff but is actually the larvae or egg cases of the Cheyletiella mites. These mites are ectoparasites that live on the skin and fur of the animal, and their presence leads to the typical movement observed, giving the appearance of 'walking' dandruff as it shifts about when the cat moves. This condition is generally visible on the fur and can be quite pronounced, making it a distinctive feature of this parasitic infestation.

The other options do not accurately capture the essence of Walking Dandruff. Static flakes would not convey the dynamic movement associated with the mites. While skin allergies can cause other types of skin issues, they do not specifically relate to the symptoms of Walking Dandruff, nor do they involve the presence of a moving substance. Similarly, while internal parasites can cause other health issues in cats, they are unrelated to the condition presented by Cheyletiella mites on the skin's surface. Therefore, the option highlighting the moving white substance correctly identifies the unique characteristic of Walking Dandruff in cats.
