What term describes the specialized hairs that make up cat whiskers?

1. Vibrissae

2. Tactile

3. Guard

4. Undercoat

The correct answer is: Tactile

The specialized hairs that make up cat whiskers are known as vibrissae. These hairs are a type of sensory organ that is highly sensitive to touch and vibrations, allowing cats to detect changes in their environment. Vibrissae are typically found on the muzzle, above the eyes, and on the forelegs of cats. They play a critical role in navigation, hunting, and spatial awareness, as they help cats assess their surroundings, especially in low-light conditions. While the term "tactile" also relates to touch and sensitivity, it does not specifically refer to the specialized hairs themselves. Guard hairs refer to the longer, coarser hairs on animals that provide protection and insulation, while undercoat refers to the softer, denser layer of fur beneath the guard hairs that helps with warmth. Thus, the term vibrissae specifically identifies these unique sensory hairs in felines, highlighting their importance in the cat's sensory perception.
