What should be monitored in rabbits to assess their health?

Monitoring common symptoms such as lethargy in rabbits is crucial for assessing their overall health. Lethargy can indicate underlying health issues such as infections, pain, or other serious conditions that require immediate attention. If a rabbit suddenly becomes inactive or is less responsive than usual, it may signal that something is wrong, prompting further investigation or contact with a veterinarian. Regularly observing a rabbit's energy levels can help identify changes early, which is essential for timely care and treatment.

While the other options can provide insight into certain aspects of a rabbit's health, such as dental issues or abnormal fur shedding, they do not encompass as broad or critical a spectrum of health indicators as common symptoms. Monitoring more general behavioral changes, including lethargy, gives a more comprehensive view of a rabbit's wellbeing.
