Product Info:

FELISINE, a palatable paste specially formulated for cats containing L-Lysine. FELISINE provides a new option for managing complications associated with Feline Herpesvirus (FHV-1) infections.


Each gram of FELISINE paste contains 250mg of L-Lysine in a palatable gel.


Feline Herpesvirus: Feline Herpesvirus (FHV-1) infection is a common cat disease characteriSed by symptoms like sneezing, nasal and ocular inflammation, corneal ulcers, and fever. Surveys indicate that up to 97% of cats carry this virus. After initial exposure, the virus remains in the animal and enters a latent state in nerve tissue near the brain. During periods of stress, the virus can reactivate and cause corneal damage in one or both eyes. Stressful situations for cats can include the introduction of a new cat or dog to the household, relocation, or even the owner’s absence during a vacation.

L-Lysine Supplementation: While there is no known cure for FHV-1, the condition can be managed. Studies have demonstrated that cats supplemented with the appropriate dose of L-Lysine experience less severe clinical signs of FHV-1 compared to those given a placebo. The amount of L-Lysine normally obtained through a cat’s regular diet is insufficient to inhibit FHV-1 replication. In another study, cats exposed to stressful conditions that induce viral shedding showed reduced viral shedding after oral administration of L-Lysine.


FHV-1 replication and growth require the presence of arginine, an amino acid. L-Lysine, when administered as a supplement, competes with arginine, thereby inhibiting viral replication. L-Lysine supplementation does not affect the plasma concentration of essential amino acids and does not cause arginine deficiency in cats.


The recommended dosage is as follows:

  • Adult cats: 1 to 2 grams of FELISINE paste twice a day.
  • Kittens: 1 gram of FELISINE paste twice a day (equivalent to 1.5cm of gel). Cats prone to recurrent FHV-1 infections or those who have experienced more than two reactivation episodes should be placed on long-term FELISINE supplementation.
