What is the black crust around cats eyes?

The darkened coating encircling your feline’s eyes is a blend of grime, discharge, and dehydrated tears.

Cats generate tears to naturally cleanse and moisten their eyes, but on occasions, their tear ducts may clog or inflame, causing an overflow of tears. This overabundance of wetness can blend with filth and germs, which ultimately results in the development of hardened build-ups encrusting the eyes.

Although more prevalent in some cat breeds, the black crust can develop around any cat’s eyes. The condition is frequently observed in cats with flat faces like Persians and Himalayans since they have shorter tear ducts.

The appearance of a dark crust near your feline’s eyes could indicate an underlying health problem.

Hence, it’s crucial to be mindful of your pet’s overall health and demeanor. In the upcoming section, we will delve into some probable reasons behind the occurrence of black crust around cats’ eyes.
