Pure L-Lysine Supplement for Cats - With Added Immune-Supporting Vitamins | Chicken Flavored Powder with Precision Dosing Spoons | 100g

Is Your Cat Struggling with Respiratory Issues or Stress-Related Flare-Ups?

Up to 97% of cats show evidence of exposure to feline herpesvirus (FHV-1) at some point in their lives. Once infected, cats carry the virus forever—and stress, illness, or a weakened immune system can trigger flare-ups at any time. Sneezing, watery eyes, nasal congestion, and eye discharge are common signs that your cat's system needs support.

Why L-Lysine for Cats?

L-Lysine is an essential amino acid that cats cannot produce on their own—they must get it from their diet. While many veterinarians have traditionally recommended lysine supplementation to support cats dealing with respiratory challenges, the most important thing is giving your cat's immune system every advantage during times of stress.

  • Immune System Support: Helps support normal immune function and antibody production
  • Respiratory Comfort: May help support normal respiratory health during seasonal challenges or stressful situations
  • Eye & Nasal Health: Supports overall comfort during periods of ocular and nasal irritation
  • Stress Response: Particularly helpful during stressful events like boarding, vet visits, new pets, or household changes

Especially Helpful For:

  • Cats with a history of upper respiratory issues
  • Multi-cat households where stress and exposure are common
  • Shelter or rescue cats transitioning to new homes
  • Senior cats or kittens with developing immune systems
  • Any cat during stressful life changes

What Makes Our Formula Different:

  • Enhanced Formula: Pure L-Lysine plus Vitamin C, B6, B12, and A for comprehensive immune support
  • Contains Cysteine & Arginine: Additional amino acids to support overall health
  • Chicken-Flavored Powder: Cats love the taste—mixes easily with wet or dry food
  • Precision Dosing Spoons Included: 1g and 5g spoons for accurate, hassle-free dosing
  • No Guesswork: Clear dosing guidelines based on your cat's age

Easy Daily Routine: Simply add to your cat's wet or dry food once or twice daily. The chicken flavor makes it palatable for even picky eaters. Most cats don't notice it's there.

Dosing Guidelines:

  • Kittens (2-3 months): 1g per dose, twice daily
  • Cats (3+ months): 2g per dose, twice daily
  • Adjust as needed based on your cat's response
