Hey all. I usually use silica bead litter because my cat is pure white and clay litter makes him very dirty. A few months ago, however, I ran out of litter and happened to have a bunch of clay litter from an ex-roommate, so I decided to use the last of it. After a few days my cat developed huge black eye goobers, clay was stuck in his chin fur, and he was totally dirty. So, I went back to using the silica litter. The problem is that ever since then he still has black eye goobers. It's been months since I've used the clay litter and I've bathed him and had his fur shaved even, and he still has black eye goobers. I didnt want to pick them off and hurt his eyes, so I left them alone for a long time, thinking they would go away on their own... which they didnt, so i started picking them off, and the next day they are back. Is there anything I can do to prevent them? Or any tips on cleaning them so I dont hurt his eyes?
