Thanks Badger. It's not a repeat issue, it's ongoing and has been present at each one of his vet visits throughout his life, it's not something that goes away and comes back, it's just the way he is.
Other then this issue being unsightly (which I have neglected to inquire specifically about with the vet and has raised no red-flags at check-ups) he is a perfectly healthy cat and shows no signs of ill-health. Just to be clear - his eyes aren't bleeding, just what the discharge/tears looks like when dried.
I'm just more curious what causes it (especially in one cat and not the other) or about 'tearing' and if there is anything I can do to lessen it, or we can just continue to deal with it has we have over the last 8 years
