🐱 VetriScience Lysine Plus: Immune Support for Cats Made Easy
Keeping your cat healthy means more than just a good diet and regular vet visits — it’s also about boosting their immune system. Especially for cats prone to upper respiratory infections or feline herpesvirus (FHV-1), a targeted supplement can make a big difference. One of the most trusted products in this category is VetriScience Lysine Plus, a vet-recommended formula designed to support immune health, respiratory function, and eye comfort in cats of all ages.
Let’s take a closer look at how this supplement works, what makes it stand out, and why many U.S. cat owners are adding it to their daily routines.
🌿 What is VetriScience Lysine Plus?
VetriScience Lysine Plus is a soft chew supplement formulated specifically for cats. It contains L-Lysine, an essential amino acid that supports immune system health and helps manage symptoms related to FHV-1 (feline herpesvirus). FHV-1 is a common virus that causes sneezing, watery eyes, nasal discharge, and even lethargy — especially in kittens and stressed cats.
Each soft chew delivers a precise dose of lysine in a tasty chicken liver flavor that most cats love, making it easier for pet parents to provide consistent daily support.
🧪 Why L-Lysine Matters for Cats
L-Lysine works by interfering with the replication of the herpesvirus in a cat’s body. It may reduce:
Eye irritation
Sneezing and nasal discharge
Inflammation in the respiratory tract
Recurrence of cold-like symptoms
In addition to immune support, L-Lysine also promotes overall health and helps stressed or sick cats recover faster.
✅ Key Benefits of VetriScience Lysine Plus
Here’s why VetriScience Lysine Plus stands out as a daily supplement for cats:
🛡️ 1. Immune System Defense
Lysine helps strengthen your cat’s ability to fight off infections — especially those caused by viral agents like FHV-1.
🐾 2. Respiratory & Eye Comfort
Cats with herpesvirus often suffer from eye discharge, inflammation, and upper respiratory issues. This supplement helps reduce flare-ups and supports easier breathing.
🍗 3. Tasty Soft Chew Format
No more struggling with pills! VetriScience Lysine Plus comes in a soft chew that cats enjoy like a treat. The chicken liver flavor is a big hit with picky eaters.
🔒 4. Safe for Long-Term Use
Formulated by veterinarians, it’s safe for daily use and ideal for long-term support, especially in multi-cat households or shelters where FHV spreads easily.
🧳 5. Great for Travel Stress
Cats are sensitive to changes. Traveling, moving, or a new pet at home can trigger immune system stress. Giving VetriScience Lysine Plus daily helps keep them balanced and calm.
🐱 Who Should Use It?
VetriScience Lysine Plus is great for:
Cats diagnosed with feline herpesvirus
Shelter cats or rescues exposed to stress
Kittens with developing immune systems
Senior cats who need respiratory support
Cats with frequent eye or nasal discharge
It’s also recommended during seasonal changes, when immune support is more important.
🥄 Dosage & How to Give
Feeding instructions (as per product guidelines):
Kittens: 1 soft chew twice daily

You can give it directly by hand or crumble it over wet or dry food. Most cats think it’s a treat!
