The easiest way to remove retained eyecaps is to put a little drop of mineral oil on your finger and rub it over his eye....it doesn't hurt, just let that soak in good....I usually wait overnight. Then take a damp Qtip and it should roll right off. Be sure to coat the eye pretty good, especially if you think he has more than one eyecap retained. You may have to do this a couple of ties to remove them all. I have never had this not work. Good Luck!
