What is NOT one of the four types of fur?

Silky fur is not considered one of the four main types of rabbit fur. The four primary types of fur recognized in rabbit classification are Rex, Satin, Angora (or Wool), and Normal. Each type has distinct characteristics that affect both the appearance and texture of the fur.

Rex fur is known for its short and velvety texture due to a unique gene that alters how the hair follicles are structured. Satin fur features a glossy sheen due to a particular type of reflective hair structure. Angora or Wool fur is characterized by its long, soft, and fluffy appearance, commonly used in textiles.

Silky fur, while it does offer a soft texture, does not fit into these established categories, making it the correct choice for what is not considered one of the main types of rabbit fur. Understanding these classifications is critical for rabbit care, breeding practices, and judging in show competitions, as they highlight not only the aesthetic appeal but also the care requirements for each type.
