Pet Cataract Symptom Guide | What to Watch For and When to Seek Care
Understand possible causes of Cataract and key home observations
Lens opacity can gradually affect vision and mobility. Record changes and schedule a veterinary examination promptly if vision changes or abnormal activity appear.
What this symptom means clinically
A cataract is loss of lens transparency caused by lens protein degeneration, fiber disruption, or altered water balance. The opacity scatters light and reduces light transmission, lowering image clarity at the retina and changing how the animal responds to light and its environment.
🐱 In cats
Cataracts are less common in cats than in dogs and are often associated with eye trauma or intraocular inflammation. Signs may be subtle.
🐶 In dogs
In dogs, cataracts are common with aging or inherited disease and may also develop secondary to metabolic disease, such as diabetes, or inflammation. The course and causes vary.
