Which factor does NOT influence showmanship success in cavy competitions?

The success in showmanship at cavy competitions is influenced by a variety of factors that are all based on preparation, knowledge, and presentation skills, rather than chance or random occurrences. Knowledge of breed standards ensures that participants understand the specifics of what judges are looking for, including traits that define quality in cavies. Having a visually appealing coat and markings plays a crucial role, as a well-groomed cavy can attract positive attention and showcase the owner’s care and dedication. Additionally, proper training and handling are vital since the way a cavy is presented can greatly impact the judges' impression, with well-trained animals exhibiting better demeanor and poise.

In contrast, random luck does not play a constructive role in showmanship success. Showmanship is about the skills and preparation that one can control and perfect, rather than relying on chance. Therefore, while luck may occasionally influence outcomes in competitions, it is not a determining factor in consistent success within the context of cavy showmanship.
