Injury A single watery or cloudy eye may be the result of an injury. Abrasions, cuts, or punctures of the eye can result from accident, hay pokes, or fighting. Examine the eye closely, especially around the rims. Sometimes a bit of hay will work itself up behind the eye and if it's partially visible can be pulled out by tweezers. If the eye shows signs of abrasion or clouds over in any way, or looks red in the white area, or seems to be swollen or sinking or squinting - get your guinea pig to an experienced veterinarian. 应该又是这种情况吧
