Why does a cat have brown crusts in the corners of its eyes? - briefly
The brown crusts in the corners of a cat's eyes are commonly due to porphyrins, a pigment produced by the breakdown of red blood cells. These crusts are typically harmless and can be gently cleaned with a damp cloth. If persistent or accompanied by other symptoms, consult a veterinarian.
Why does a cat have brown crusts in the corners of its eyes? - in detail
The presence of brown crusts in the corners of a cat's eyes is a common occurrence and is often referred to as "eye boogers" or "sleepies." These deposits are primarily composed of dried mucus, oils, and other secretions from the tear ducts.
Cats, like humans, produce tears to maintain eye health and moisture. However, unlike humans who typically blink more frequently, cats tend to have a slower blinking rate. This can lead to an accumulation of these substances in the corners of their eyes, which then dry out and form crusts. The brown color is usually due to the presence of porphyrins, naturally occurring compounds found in cat tears that react with light and air to turn brown.
Several factors can contribute to the formation of these crusts:
- Age: Older cats may produce more tears and have less efficient tear drainage systems.
- Health Conditions: Certain health conditions, such as allergies or infections, can increase tear production.
- Diet: A diet rich in fish oil supplements or certain types of food can alter the composition of tears.
- Eye Anatomy: Some cats may have structural issues with their tear ducts that lead to more significant buildup.
While these brown crusts are generally normal, excessive or persistent discharge can be a sign of an underlying issue. Regularly cleaning your cat's eyes using a warm, damp cloth can help remove the deposits and prevent any potential irritation or infection. If you notice any changes in the amount or color of the discharge, or if your cat shows signs of discomfort such as squinting or pawing at its eyes, it is essential to consult with a veterinarian for proper diagnosis and treatment.
