Which factor is NOT likely to help a cavy feel comfortable in a show?

A cavy's comfort in a show setting can be significantly influenced by environmental factors and the animal's prior experiences. A quiet environment is conducive to reducing stress, as it minimizes the chance of startling the animal with sudden or loud noises. Similarly, if a cavy is accustomed to being handled by its owner, this familiarity contributes to a sense of security, helping the animal feel more relaxed during the show. Additionally, having familiar items nearby—such as bedding or toys—provides a sense of comfort and assurance in an unfamiliar setting.

Exposure to loud noises, however, is not beneficial for a cavy's comfort. It can induce stress and anxiety, making the animal more agitated and likely to exhibit fearful behaviors. Thus, this factor would not help a cavy feel comfortable in a show environment, leading to a less favorable showing experience.
