Lysine for flare-prone cats

The pattern is familiar to most multi-cat households: routine breaks — a move, a guest, a new animal — and within days one cat's eye is weeping and half-shut. That is the classic rhythm of feline herpesvirus, which most cats carry quietly and stress wakes up.

L-Lysine is the long-standing supplement answer: an amino acid given daily as quiet background support. The Optixcare powder measures it at 500mg a scoop, and the scoop stirs clean into wet food — which matters, because the entire strategy depends on the cat not knowing it's being supplemented.

The habit is the treatment: daily through calm seasons, not scrambled during flare-ups. Owners who keep the scoop constant report fewer and shorter episodes; owners who dose only when the eye is already angry are always a week behind the virus.

And the honest boundary: lysine is support, not medicine. An eye that is red, painful, or discharging needs a veterinary exam and likely an antiviral — the scoop resumes its quiet work after the all-clear.
