L-Lysine is used to treat cats with feline herpes or cats with upper respiratory infections. Though there is no cure for feline herpes, L-Lysine works uniquely to combat both the virus itself and the symptoms that it causes. Upper respiratory infections are one symptom of the herpes disease, and so it is important to use L-Lysine to prevent these dangerous complications.
L-Lysine is available in a wide variety of supplements that are listed below. Find the right supplement to treat your cat's FHV outbreaks today!
