What is a common sign of a mouse suffering from respiratory issues?

1. Coughing

2. Rapid weight loss

3. High activity levels

4. Bright eyes

The correct answer is: Coughing

Coughing is a common sign of respiratory issues in mice, which can be indicative of underlying health problems such as infections, allergies, or environmental irritants. When a mouse exhibits coughing, it may be attempting to clear its airways or is experiencing discomfort in its respiratory system. This symptom can be particularly concerning as it often suggests that the mouse is struggling to breathe properly or is affected by pathogens that target the respiratory tract. In contrast, rapid weight loss is generally associated with conditions like malnutrition or systemic illness rather than specifically respiratory problems. High activity levels would typically indicate good health and vigor in a mouse, whereas bright eyes are a sign of alertness and health. Therefore, coughing stands out as a direct and recognizable indication of respiratory distress in mice.
