What is a fault in cavy showmanship?

A fault in cavy showmanship refers to an issue that is present in the cavy or the presentation that is not severe enough to disqualify the competitor from the event. This means that while the fault may detract from the overall quality or presentation, it does not reach a level of seriousness that would eliminate the cavy from competition. Recognizing faults is part of the judging process, as they provide a basis for assessing the overall quality and presentation of the competitor's cavy.

The other choices either misinterpret the nature of a fault or suggest concepts that do not align with cavy showmanship practices. An error in presentation indicates a mistake made by the handler, which could contribute to a fault but is distinct from it. A disqualification that allows for a second chance is contradictory since a disqualification typically means the competitor cannot compete further. Lastly, an attribute that enhances a cavy's appearance is unrelated to faults, as it speaks to positive traits rather than issues that detract from the animal's quality. Therefore, identifying a fault correctly reflects understanding the standards of competition.
