Health Impact on Cats’ Eye Color Change

Several health issues influence your cat’s eye color change. Primarily, uveitis and high blood pressure result in color alterations. For instance, uveitis causes inflammation in the feline eye, shifting its color from its usual hue to a darker tone. High blood pressure, on the other hand, leads to blood vessels in the eyes bursting, causing the eye color to lighten.

There’s also a visible thickening in the eye’s cornea, causing it to appear cloudy. Cats suffering from high blood pressure may exhibit lethargy and loss of appetite. Additionally, their pupils may remain persistently dilated.

For instance, uveitis requires anti-inflammatory medication, while high blood pressure calls for reducing salt intake and incorporating blood pressure-lowering drugs in the diet.

Neglecting these health implications may lead to dire consequences such as loss of vision. About 60% of cats untreated for hypertension suffer from blindness, while untreated uveitis can lead to cataracts, glaucoma, and also irreversible blindness.

However, eye color change doesn’t always indicate sickness. Genetic traits cause blue-eyed kittens’ eyes to darken as they mature, exhibiting amber, green, or gold shades.
