What is a cataract in guinea pigs?

A cataract in guinea pigs refers to a disease of the lens of the eye. This condition results in the lens becoming cloudy, which can impair vision. Cataracts may develop due to factors such as aging, genetic predisposition, or certain health conditions. When the lens is affected, it can lead to difficulties seeing, which may impact the guinea pig's ability to navigate its environment, find food, and interact with others.

The other options focus on unrelated health issues that do not pertain to the eye or vision. Skin diseases would impact the cavy's coat and overall skin health, dental problems involve the condition of the teeth, and ear infections pertain to issues in the auditory system. None of these choices address the specific nature of a cataract, which is solely related to the eye and its lens.
