Lysine for cats is used to treat cat issues like upper respiratory problems or herpes. It is effective to improve symptoms of upper respiratory infection and also inflammation and conjunctivitis caused by herpes.

Why Lysine for cats?

Lysine is a dietary supplement for cats, as it controls all the symptoms that can lead to feline herpes and other infectious diseases. It is a type of protective layer for the cats. Feline herpes is highly contagious, which causes upper respiratory infections and painful discharge from eyes. It is an airborne virus which can be spread very easily and quickly from one cat to the other, especially cats living together under one roof. It is also called conjunctivitis, which if not cured on time can lead to blindness of your cat. Feline herpes spreads in cats, but cannot spread to humans. Most cats already are infected with feline herpes, so it is important to conduct a complete medical checkup before taking a pet home.

Like humans, cats also have feelings. They also go under stress, illness, poor diet, fleas or other things like this which affect their body and immune system negatively. If your cat has once been cured from feline herpes, the above mentioned conditions can cause the disease to re-emerge. However, lysine for cats can boost the immune system to fight against viruses. It is easily available without prescription.

Lysine for cats


If you feed your cat with lysine supplements, then you are most likely preventing your pet from the following diseases:

  • Conjunctivitis
  • Upper respiratory infections
  • Cold sores
  • Feline herpes
  • Fever blisters
  • Sneezing
  • Difficult breathing
  • Sinus congestion
  • Squinting
  • Lethargy
  • Sore throat and mouth

However, this is not a permanent and direct cure, but it is clinically proven to protect the cats from getting exposed to harmful infectious diseases. It decreases the possibility of your cat falling sick due to the above mentioned diseases by slowing down the growth of viruses.

How does lysine work?

Once the viral DNA enters the host’s cell, it starts to grow. The host cell is then unable to distinguish between its own DNA and the viral DNA. So, as per routine, the host cell continues to make more viruses until it bursts and spreads in the body to infect more cells. The infected cells use an amino acid named arginine to make more copies of the viral cells. When a cat is fed lysine, the chemical processes are limited because of L-Lysine (amino acid present in lysine). With the daily dose of lysine supplements, you provide your cat with the ability to increase the quantity of L-Lysine which it can use to perform its natural functions. This leads to less arginine, which is not enough to produce or spread viral DNA.


By administering the daily dosage for cats you can ensure its good health. You can be sure of protecting it from the life threatening diseases, also preventing the cat from future infections.
