Which condition is not considered a disqualification for a cavy?

Having a noticeable coat sheen is not considered a disqualification for a cavy. In fact, a healthy sheen on a cavy's coat can indicate good grooming and overall health. This characteristic is typically viewed positively among judges, as it demonstrates that the cavy is well cared for and has a shiny, healthy appearance.

In contrast, the other conditions mentioned—fur or eyes being the wrong color for the breed, extra or missing toes, and malocclusion—are specifically outlined as disqualifications in cavy standards. These issues can affect the cavy's conformance to breed standards and overall health, leading to them being grounds for disqualification during shows. Understanding the specific criteria that judges consider in showmanship is crucial for anyone involved in exhibiting cavies.
