Cat herpes is a cause of corneal and conjunctival inflammation. This condition, when untreated, may worsen and aggrevate continual outbreaks.L-lysine (500 mg in one package) blocks replication of inflammation. In order to avoid vomiting, felines should be given L-lysine only when mixed with wet food.
If you are using eye drop for your cat, however, please see your veterinarian in advance.
