In cats, cataracts exist when there is opacity in the eye's lens rather than the original translucency. Because the lens has become opaque, transmission of light to the eye's retina may become blocked, preventing the cat from seeing properly. There are a number of causes for cataracts, and they cannot be completely reversed. Cataracts cannot be completely prevented, but there are treatment options for reducing the impact of a cataract when it first begins to become a problem for the feline.

Warning Signs
-
The first warning signs associated with cat cataracts include a color change inside of the eyes, and changes in the cat's behavior. The cat may suddenly appear clumsy, running into walls or stumbling unexpectedly. The cat may also appear reluctant to use stairs or to climb or jump up onto different objects. In unfamiliar environments, the cat may appear hesitant. Other symptoms include squinting, redness in the eyes and inflammation in the eyes.
Diagnosis
-
Diagnosis of cataracts in a cat begins with a physical examination, including a full eye examination. Blood tests, ultrasound examinations and electroretinogram tests may also be required in order to determine the underlying cause for the cataracts. If there is an underlying reason for the development of a cataract, it must be treated first before the cataract can be properly treated. Proper diagnosis is important for cat cataract issues.
Treating the Underlying Cause
-
Treating the underlying cause of the cat cataracts is necessary before anything can be done about the development of the cataracts themselves. Without treating the underlying reason for the development of cataracts, the development will only worsen rather than improving. Treatment, then, needs to be aimed at addressing the underlying cause before anything else can be done.
Treating Inflammation
-
When inflammation or uveitis is the underlying cause for cataracts within the eyes, anti-inflammatory or antibiotic drugs will be prescribed to improve the inflammation. Treating the inflammation should slow down or cease the development of cataracts. Inflammation can sometimes point to an even deeper underlying cause, however.
Surgical Options
-
If a cataract is inherited, or if it appears to appear spontaneously, it may be capable of being surgically removed. When cataracts develop as a result of inflammation in the eye, they cannot be surgically removed unless the inflammation has been reduced or cured. Many cats that have cataracts are not good candidates for surgical options because there is inflammation present within the eyes.
