Let's talk about eye goop. *grin* Eye goop can range in color and consistancy from clear and watery to thick, green pus-like discharge. In order to determine whether or not you should attempt to treat the problem yourself, you have to examine the eye goop. If it is anything but thick, yellowish-green, pus-like discharge, the chances are very good that you can treat it at home, but if it is thick, yellowish-green, pus-like discharge, immediately seek a vet's professional advice and treatment, do not pass Go, do not collect $200.
OK, so you have now examined the eye goop and it is not thick, yellow-ish green, pus-like discharge. You can attempt to treat it at home, but you have to have a few things on hand first, so make a list and run out to the nearest store to collect what you need:
Antibacterial Hand Soap
Cotton Gauze (NOT Cotton BALLS)
One Deep Bowl - Wash before use, preferably in dishwasher with heat dry setting
8x8 inch Ceramic or Pyrex Casserole dish, washed in dishwasher with the heat dry setting
Large Bottle of Alcohol
Wash your hands all the way up to your elbows in hot water (as hot as you can reasonably stand) and the antibacterial hand soap. Leave the soap on your skin for at least 3 minutes and rinse then dry thoroughly with a clean paper towel. Place the scissors in the 8x8 dish so they lay flat and pour alcohol in to cover the scissors completely. Soak for 10 minutes, remove and dry thoroughly with a clean paper towel. Using the clean, dry scissors, cut several small pads of the cotton gauze, approximately 3 inches by 3 inches. Fill the deep bowl with warm, NOT HOT water. Dip a piece of the gauze you have cut into the water and lightly wring. You don't want it to be dripping, but you don't want it to be dry either. GENTLY, dab the eye, do not wipe or rub, just dab the eye with the wet gauze to soften the crust. Repeat this several times but DO NOT ATTEMPT TO PRY THE EYE OPEN. You just want to soften the crust and remove it gently with the gauze.
Repeat this process twice a day for several days or until the eye is completely open and free from any further discharge or crust.
If, while cleaning the eye, you notice that the discharge has turned yellow-ish green and is thick or pus-like, stop treating the eye immediately and call your vet for an antibiotic eye ointment as well as instructions on how to administer it to your kitten.
Hope this helps,
