Why is proper lighting important in a show environment for cavies?

Proper lighting is essential in a show environment because it allows judges to better assess the cavy’s appearance. Good lighting ensures that the judge can see the cavy clearly, evaluating factors such as coat quality, structure, and overall condition without shadows or distortion that can occur under poor lighting. This clarity is crucial for making accurate assessments of the animal's conformation, grooming, and any potential health issues. Highlighting the cavy's features effectively also assists the judge in determining if the cavy aligns with breed standards, ultimately influencing scoring and placement in the show.

The other options, while they may have some merit in certain contexts, do not directly address the primary function of lighting in a judging scenario. For example, lighting does not create temperature comfort for the cavies, nor is it primarily designed to help them see better, as cavies rely more on their other senses. Additionally, while good lighting can enhance the visibility of a cavy's color, the primary importance in a show setting remains the clear assessment of their overall appearance by the judge.
