What properties of fur are there?

Fur possesses several key properties, including insulation, which helps regulate body temperature by trapping air and retaining warmth. It also has water-resistant qualities, as the outer layer can repel moisture, keeping the underfur dry. Additionally, fur provides a degree of camouflage, aiding in the animal's survival by blending into its environment. Lastly, the texture and color of fur can vary widely among species, serving both functional and aesthetic purposes.
