Cat Cataracts: Everything You Need to Know


Cat cataracts are a medical condition that affects the lenses of a cat’s eyes, leading to cloudiness and decreased vision. Cataracts can develop due to various factors, including age, genetics, diabetes, and certain infections.

Cat Cataracts

A cataract is a change in your cat’s lens that prevents light from reaching the retina, which houses their vision cells, in that eye. The majority of cataracts begin tiny, but they may develop and expand to a density that impairs vision. Some cataracts remain static rather than growing. The little eyesight loss caused by such cataracts is readily adjusted by cats.

A lens alteration known as nuclear sclerosis often occurs as people age. This issue often manifests simultaneously in both eyes. Although it has a similar appearance (a haziness in the eyes), your cat’s eyesight is typically not significantly affected.
