What are common reasons for disqualification in cavy showing?

In cavy showing, disqualifications are primarily concerned with the health and structural integrity of the animal, which is why illness, malformations, and non-conformity to breed standards are key reasons for disqualification. If a cavy exhibits signs of illness, it poses a risk not just to itself but also to other animals present, making it a critical factor in judging. Malformations can indicate poor breeding practices or health issues that affect the cavy's ability to compete fairly. Furthermore, compliance with breed standards is essential, as shows are designed to showcase the best representatives of each breed. A cavy that deviates significantly from these standards, whether in physical appearance or health, cannot be judged fairly against those that meet the criteria.

In contrast, factors like age, breed type, or size may be important in classifications but aren't typically grounds for disqualification unless they result in health issues or significant breed standard deviations. Weight, color, and coat length are usually part of the assessment criteria rather than disqualifiers. Temperament or grooming style, while relevant to a competitor's overall presentation, are also not typically disqualifying factors in the formal judging process. Therefore, the focus on health and structural correctness establishes option B as the most relevant choice
