What physical symptom is commonly associated with weight loss in rabbits?

Weight loss in rabbits is often closely linked to loss of appetite. When a rabbit is not eating properly, it will naturally lose weight over time, as its caloric intake is significantly reduced. A decrease in appetite can indicate various underlying health issues such as dental problems, gastrointestinal disturbances, or other systemic diseases. Therefore, when a rabbit is experiencing weight loss, it's important to assess its eating habits to determine the cause, making loss of appetite a critical symptom to observe.

Excessive fur loss might indicate external factors like stress or skin conditions, but it isn't directly tied to weight loss. Puffy cheeks could suggest dental problems or infections, but they wouldn't necessarily lead to a loss of weight on their own. Increased chewing behavior might suggest boredom or a need to wear down teeth, rather than a symptom reflecting weight loss. Hence, loss of appetite is the most direct and relevant symptom associated with weight loss in rabbits.
