one of my cats, thomas o’malley, has really bad runny eyes. it’s sort of a rust color. not as much when he’s awake, but really bad after he wakes up. my vet took a look and said it could be a variety of things (as did google) and, being a boy on a budget, suggested we try l-lysine for cats first…before running tons of expensive tests.
i’m happy to say it cleared him up! not completely, as he definitely has a long-term issue, but i’m highly recommending this to any of you who google this cat health problem. (always confer with your vet, first!)
