Why is the weight of a cavy important during a show evaluation?

The weight of a cavy is crucial during a show evaluation because it serves as an indicator of the animal's overall health and development. A cavy that is appropriately weighted for its age and breed demonstrates that it has received proper nutrition and care, which is essential for optimal growth. Healthy weight is indicative of good husbandry practices, and it can directly influence a judge's assessment of the cavy's fitness for exhibiting. Additionally, a cavy that is underweight may be seen as potentially unhealthy, while one that is overweight may signal overfeeding or lack of exercise. Therefore, weight is a practical measure of a cavy's well-being, which is a top priority in show evaluations.
