We raised a lot of cats growing up in the south, and it is VERY common for kittens to get eye boogers to the point where if you dont wipe it with a damp cloth, it will hold their eyes shut. In cats, it's also much closer to the consistency of butter than in humans.   Im willing to bet it may have something to do with that.

That actually sounds like cat herpes. That's a common symptom of it.
