What is the role of a cavy's whiskers?

The primary role of a cavy's whiskers is to assist in navigation and enhance spatial awareness. Whiskers, also known as vibrissae, are highly sensitive tactile hairs that provide caviies with important sensory information about their environment. These specialized hairs are capable of detecting subtle changes in their surroundings, allowing cavies to navigate through tight spaces and avoid obstacles. This sensory feedback is crucial for their safety, as it helps them to gauge the proximity of objects and the layout of their habitat, particularly in low-light conditions or unfamiliar environments.

While whiskers may contribute to a cavy's appearance, the main function is sensory rather than aesthetic. Additionally, they do not play a role in thermoregulation or attractiveness in mating scenarios. Instead, their primary function is rooted in survival and helping the animal interact with its environment effectively.
