What should a handler observe for in a rabbit with respiratory symptoms?

A handler should look for mucus on the face and forelegs of a rabbit showing respiratory symptoms because this indicates the presence of a respiratory infection or illness. The secretion of mucus can occur when the respiratory tract is irritated or inflamed, which is common in cases such as rabbits suffering from respiratory infections like snuffles (Pasteurellosis). Observing mucus can provide crucial information about the health status of the rabbit and is a key indicator that further veterinary assessment may be necessary.

In contrast, gaining weight and increased energy would typically suggest the rabbit is in good health rather than experiencing respiratory distress. Less grooming behavior, while it might indicate illness, does not provide the same clear and direct link to respiratory issues as visible mucus does. Mucus serves as a tangible sign that helps in diagnosing and addressing the underlying health problems affecting the rabbit's respiratory system.
