How should a cavy's ears appear in shows?

A cavy's ears should appear clean, upright, and free of wax build-up during shows because this not only reflects good health and grooming but also aligns with breed standards. Ears that are upright indicate alertness and good condition. Clean ears suggest that the owner has taken the time to maintain proper hygiene, which is essential for the overall well-being of the animal. Wax build-up can signal neglect or health issues, which judges assess when evaluating the animal's care.

The other options do not adhere to the standards commonly valued in competition. Floppy or droopy ears would not reflect the ideal posture for many cavy breeds. Large and fuzzy ears may not conform to specific breed characteristics. Short and flat ears against the head could indicate a conformation that is not desirable for show purposes, unless specifically called for in certain breeds. Overall, the ideal appearance of a cavy's ears is an essential component of showmanship that underscores proper care and breed characteristics.
