So normally Baku has average amounts of crusties in his eyes whenever he wakes up. Sometimes though, they're HUGE and it isn't a crusty any more... it becomes a gunk. Usually it's just 1 eye with gunk, though.
I took this picture on my way into work as soon as I saw that he had a bunch. It's actually under both of his eyes.
I clean his eyes like 2-3 times a day to clear the stuff off, but what's causing there to be such a large amount? Should I take him to the vet, or is this normal?
