How is the "extra or missing toes" condition categorized?

The condition of "extra or missing toes" is categorized as a disqualification because it is considered a significant deviation from the breed standards set for cavies. In competitive showmanship, adherence to breed standards is crucial, and certain physical traits are non-negotiable; the presence of extra toes or the absence of required toes directly impacts the animal's conformity to these standards. As a result, cavies exhibiting these traits cannot compete in shows, emphasizing the importance of genetic soundness and breed integrity in judging.

The other categories, while addressing aspects of cavy presentation, do not encapsulate the seriousness of this condition in the context of competitive showing. Minor faults generally refer to less severe deviations that may not exclude an animal from competition, while aesthetic issues might pertain to appearance but do not affect eligibility. Genetic traits can provide context to how these characteristics arise but do not pertain to the show's rules regarding competition and disqualification.
