Cat Cloudy Eyes Lethargic. Cats that are lethargic seem depressed, are tired or sedate, sleep more than normal, and don’t play as much as usual. Infections—fighting off bacteria, viruses, or other pathogens takes a lot of energy.
Another reason for cloudy corneas, although rare in cats, is endothelial dystrophy. Watery eyes or other eye discharge can be a sign that your cat has an eye infection. Eye problems can bring out another cat entirely.
