I have one. I know that herpes eye virus in cats can't be cured and that lysine will sometimes help. What other things can I do to help prevent an outbreak of this in my cats? Since I now own 10 cats, they've been having many more eye infections than they ever used to. I got rid of the Chlamydia infections but then all of my younger cats broke out with what my vet thinks is the herpes eye infection. First it was Finnegan, then Radar, then Rory, then Reece, and then Colby. Right now they all seem fine again but for how long. I also know that stress will cause outbreaks. I was told by the pharmacy tech that it's happening because they are young cats so their immune systems aren't as good.
