Best Cat Food for Cats with Feline Herpes

by

Feline herpesvirus (FHV-1) is a common infection that causes sneezing, runny eyes, nasal congestion, and recurrent respiratory symptoms in cats. While there is no cure, you can support your cat’s immune system and quality of life through thoughtful nutrition and a stress-minimized environment. Here’s how to feed your cat for comfort, healing, and resilience against flare-ups.

Understanding Feline Herpes (FHV-1)

Feline herpes is a lifelong viral infection. Many cats catch it as kittens, and symptoms can return during times of stress, illness, or poor nutrition. Typical signs include:

  • Frequent sneezing
  • Runny eyes or nose (sometimes with discharge)
  • Eye ulcers
  • Congestion, snoring, or labored breathing
  • Lethargy or decreased appetite during flare-ups

While medications and supportive care are the mainstays of treatment, diet makes a meaningful difference in how often and how severely your cat gets sick.

Dietary Goals for Cats with Feline Herpes

  • Support immune health: Nutrition directly affects your cat’s ability to fight infections and recover from stress.
  • Ensure adequate hydration: Congestion and fever can cause dehydration, so moisture-rich diets are best.
  • Encourage eating: Cats with blocked noses may lose their sense of smell and appetite. Highly palatable, aromatic food helps keep them nourished.
  • Include key nutrients: Omega-3 fatty acids, antioxidants (vitamins E and C), and L-lysine (sometimes recommended by vets) can help manage symptoms and boost immune defenses.

Best Cat Food Features for Feline Herpes

  • High-moisture content: Wet/canned foods are gentler and help keep your cat hydrated, especially if they aren’t drinking well.
  • High-quality animal proteins: Essential for tissue repair and immune support. Look for real chicken, turkey, or fish as the first ingredient.
  • Limited fillers and artificial additives: Minimize unnecessary grains, dyes, and preservatives, which can stress sensitive cats.
  • Added omega-3s and antioxidants: Support healing and may reduce inflammation in airways and eyes.
  • Option for L-lysine supplementation: Some formulas include L-lysine, an amino acid that may help reduce the frequency or severity of flare-ups (always check with your vet before starting supplements).

Feeding Tips for Cats with Feline Herpes

  • Serve small, frequent meals: Offer food several times a day, especially during flare-ups, to ensure consistent intake.
  • Keep water fresh and accessible: Consider a water fountain if your cat is reluctant to drink from a bowl.
  • Add L-lysine if recommended: Discuss with your vet whether an L-lysine supplement or L-lysine-enriched food is right for your cat.
  • Minimize stress: Keep routines consistent and provide a quiet, safe environment. Stress can trigger or worsen herpes flare-ups.

When to See the Vet

  • If your cat stops eating for more than 24 hours

  • If symptoms worsen or don’t improve with supportive care

Your veterinarian can prescribe antiviral medications, antibiotics for secondary infections, or recommend additional supportive therapies.

The Bottom Line

Choose high-quality, high-moisture, palatable foods with a focus on immune health and hydration. Work closely with your vet, and adjust your feeding strategy as your cat’s needs change—especially during flare-ups. With the right approach, most cats with herpes can thrive for many years.
