Which of the following is NOT considered a fault?

In the context of cavy showmanship, "faults" are features or characteristics that detract from an animal's overall quality and adherence to breed standards. A fault can be based on physical traits or temperament that do not align with what is ideal for the breed.

Perfectly aligned stripes indicate an ideal characteristic in certain cavy breeds, particularly those that have coat patterns requiring stripes to be uniform and well-defined. This trait is often sought after in judging, as it reflects good breeding practices and adherence to the breed standard. Therefore, having perfectly aligned stripes is considered a positive attribute, not a fault, and will be rewarded in show conditions.

In contrast, small size might be viewed as deviating from breed standards depending on the specific expectations for that breed. Faulty color placement can significantly affect a cavy's scoring in a show due to its impact on aesthetics and breed characteristics. An unresponsive temperament is also a critical issue, as cavies are expected to be friendly and manageable when handled. None of these options contribute positively to the quality of the animal, making them faults, while perfectly aligned stripes enhance the cavy’s appeal and are viewed favorably.
