The Benefits of Lysine for Cats and Different Ways to Apply It
Cat Lysine or L-Lysine for cats is used to treat upper respiratory problems or feline herpes. Not only can it improve their upper respiratory infection (URI) symptoms, but also inflammation of the eyes and conjunctivitis (eye discharge) caused by feline herpes.
Health Problems Lysine Helps Prevent

Does your cat need Lysine?
L-Lysine is an important dietary supplement for cats because not only does it treat feline herpes but it also helps to prevent the symptoms. Feline herpes is highly contagious amongst cats causing upper respiratory infections and a painful eye discharge called conjunctivitis that can lead to blindness. Feline herpes spreads within cats and cannot spread from cats to humans. Most cats are infected with the feline herpes virus and the infection is lifelong.
Keep in mind, a cat's immune system is able to suppress feline herpes up to a certain point. A cat's life can be filled with stress, illness, fleas, poor diet, extreme temperatures or anything else which can negatively affect their immune system. Thus causing the feline virus symptoms to re-emerge. Since there is no cure for feline herpes, continued Cat L-Lysine supplementation can help fight against the virus and is available without a prescription..
