Take one soaked cotton ball, squeeze out any excess moisture, and hold it gently over your kitten's crusted eye. As the debris starts to loosen, wipe from your kitten's tear duct to the outer edge of the eye (gently wipe in the direction a mom cat would groom).

If you see that the eye is oozing, crusted, or sealed shut (in a kitten over 2.5 weeks), the kitten likely has an eye infection. Seek veterinary support as soon as possible. Intervene right away with steps 2-4 in order to avoid the infection worsening.

Moisten a soft cloth with warm water. Take caution not to make it too hot. Place the moist cloth on the matted eyes. Hold it there until the matted crust begins to loosen.

One of the most common causes of a gunky eye in cats is an eye infection. This can be caused by bacteria, viruses, or even fungi. Other potential causes include allergies, foreign objects in the eye, or even a blocked tear duct.
