I've been getting lysine into my cat who has had a long term eye herpes flair-up (conjunctivitis) but the supplement just isn't getting it under control. She is on a raw diet and has the most luxurious coat of any cat I know. It seems that for eye infections, drops would be the best way to get to the problem directly, so I'm wondering why there aren't lysine drops. Can I make my own with saline? I don't want to go the route of expensive antiviral drops.
