What is one of the most critical factors in cavy coat care before a show?

Ensuring cleanliness and good condition is fundamental in cavy coat care before a show because it directly impacts the overall appearance and health of the animal. A clean cavy not only has a more polished look but also demonstrates that the owner takes pride in their care. Judges often assess the condition of the coat as indicative of the animal's health and the owner's grooming practices. A well-groomed cavy with a clean coat is more likely to attract positive attention.

While some options touch on aspects of grooming, they do not prioritize the critical importance of basic cleanliness and maintenance. For example, using grooming tools can help in flattening fur, but if the fur is not clean or healthy, the results will not be impressive. Similarly, while color and shine are notable, they should not overshadow the essential requirement of good hygiene and coat condition, which is the foundation for presenting any animal at a show.
