Which of the following is a disqualification for a cavy?

Malocclusion is indeed a disqualification for a cavy because it is a serious dental issue that affects the animal’s ability to eat properly. In cavies, the teeth grow continuously throughout their lives. When the upper and lower teeth do not align correctly, which is known as malocclusion, it can lead to severe health problems, including difficulty eating, weight loss, and pain. This condition is easily identifiable during a show, making it a significant reason for disqualification.

While overgrown nails, hair loss, and excessive grooming can negatively impact the overall appearance and presentation of a cavy, they do not fundamentally impair the animal’s health or its ability to function. These issues may be considered faults in the show ring, but they do not reach the level of disqualification that malocclusion represents. Therefore, malocclusion stands out as a critical health concern that directly influences the well-being of the cavy and is thus classified as a disqualifying factor in showmanship events.
