Vetsense Lysine Paste is a nutritional supplement for cats and kittens containing 250mg of L-lysine HCl per mL. It supports immune health and is used to help reduce the severity of Feline Herpes Virus symptoms — the recurring respiratory, nasal, and eye flare-ups that many cats carry throughout their lives.

Each mL also contains high-grade fish oil, adding Omega 3 and 6 support for skin, coat, and development — particularly relevant for kittens still growing. The formula is chicken-flavoured for palatability and comes in an airless-pump dispenser that preserves product integrity over time. It can be administered directly or mixed into food.

L-lysine supplementation is a commonly recommended management approach for cats with recurring FHV outbreaks. The paste format and airless-pump dispenser make daily administration considerably more practical than tablet or powder alternatives — cats who'd stage a protest with most supplements tend to cooperate more readily with a chicken-flavoured paste.
