Can regular cleaning of my cat’s eyes prevent eye issues?

Yes and no. It depends on what eye issue we're looking at. It's not going to prevent high blood pressure, but if you have a cat with long hair or a smushed face, you want to make sure that the hair and the folds aren't rubbing on the cat's eyes or collecting matter that's rubbing on the cat's eyes. Keep it appropriately groomed and wiped away. With many cats, because of the way their facial features are, you don't necessarily have to clean their eyes every day.
