Which of the following is a key element of a cavy's general appearance?

The key element of a cavy's general appearance is best represented by the condition of the coat, body shape, and overall health. These factors are crucial because they directly influence how the cavy presents itself in a show setting. A well-groomed coat indicates good care and healthy skin, while an appropriate body shape signifies proper growth and development, essential for breed standards. Overall health reflects the animal's vitality and fitness, impacting its performance and attractiveness in a show environment.

Assessing a cavy's general appearance primarily focuses on these physical attributes, which are visible indicators of its well-being and suitability for competition. In contrast, the weight and size of the cage, color of the accessories, and age of the cavy might be relevant to care or handling but do not encapsulate the essence of general appearance in the context of showmanship.
