Finding out your cat has viral rhinotracheitis can feel scary, especially if you have other cats at home. Not only are you working hard to keep your infected cat feeling their best, but you also have to take precautions to help reduce the chance of infecting the rest of your feline household. 

The good news is that feline viral rhinotracheitis is a manageable condition, especially with early intervention and basic preventative measures.

What is Feline Viral Rhinotracheitis?

Feline Viral Rhinotracheitis (FVR) is a highly contagious upper respiratory infection caused by feline herpesvirus‑1 (FHV‑1). It’s spread through nose‑to‑nose contact, saliva, contaminated hands, and shared bowls, toys, and litter boxes.

Many infected cats carry the virus for life. It can, however, go dormant at times, meaning your cat isn’t contagious. This is called a latent chronic infection. 

Most cats with FHV-1 experience the virus reactivating (or flaring) from time to time and usually develop symptoms when this happens. During this time, they risk passing the virus to another cat through nose and eye secretions. This is called “shedding” the virus. 

Stress can trigger these flare‑ups, which is why FVR can spread quickly through homes and facilities that house cats. 

How FVR Spreads and Why It Matters

FVR spreads quickly in homes and facilities with multiple cats. During flare-ups, cats shed the virus through nose and eye secretions. Stress—such as changes in routine or environment—can trigger these flare-ups. Feline viral rhinotracheitis vaccine is your best defense against the spread and severity of the disease, even if it doesn’t provide total protection. 

FVR vs. Other Cat Respiratory Diseases

Feline Viral Rhinotracheitis Signs

Catching the early signs of FVR is key to helping your cat feel better as quickly as possible. If you see any of the following, reach out to your veterinarian right away.

Mild to Moderate Cases

• Respiratory changes, like sneezing and nasal congestion
• Eye changes, like runny, red, or inflamed eyes, eye discharge, or squinting
• Behavioral changes, like decreased appetite or low energy
• Fever

Severe Cases

• Not eating or drinking for more than a day
• Thick green or yellow discharge from the nose or eyes
• Difficulty breathing or open-mouth breathing
• Eye ulcers that look like cloudy or blue spots
• Severe squinting
• Pawing at the eyes or nose
• Ulcers in the mouth or on the face

Kittens, seniors, and cats with other health concerns often get sicker and need extra support from their veterinarian.

Feline Viral Rhinotracheitis Prevention 

Whether you’re trying to keep FVR out of your home entirely, prevent flare-ups in an infected cat, or manage a household with sick and healthy cats, here are some simple prevention tactics.

Vaccination 

The feline viral rhinotracheitis, calicivirus, and panleukopenia  (FVRCP) vaccine includes protection against FHV‑1, which causes FVR. Even if the vaccine doesn’t provide 100% protection, it does reduce the severity of infection and viral shedding, reducing the potential for the virus to spread. 

Follow your veterinarian’s recommended vaccination schedule, including important boosters for kittens. Vaccination is still recommended for cats that have previously been infected with FHV-1. 

Reducing Exposure

• Keep cats indoors or supervised outdoors
• Quarantine new cats until your veterinarian gives the all-clear (usually 3–4 weeks)
• Vaccinate new cats as soon as possible
• Don’t share supplies between sick and healthy cats: food/water bowls, litter boxes, bedding, toys

Lowering Stress to Reduce Flare-ups

• Keep routines predictable for feeding, play, cleaning, and sleep
• Provide mental and physical enrichment: food puzzles, training games, interactive play
• Offer vertical spaces, scratching posts, and puzzle feeders
• Ensure enough litter boxes (one more than the number of cats)
• Use pheromone diffusers, slow introductions, and safe retreats
• Improve relationships between pets who don’t get along well

Hygiene and Home Safety for Multi‑Cat Homes

• Wash your hands before and after handling your cats, especially if one is showing symptoms of FVR.
• Clean food and water bowls daily with hot, soapy water.
• Scoop litter boxes daily and wash boxes every couple weeks
• Wash shared soft fabrics in hot water
• Don’t share fabric items between sick and healthy cats
• Create separate areas for sick cats with their own supplies
• Keep pet-safe disinfecting wipes and a lined trash can in sick cat areas
• Provide fresh airflow to reduce saliva droplet buildup

The most important thing you can do is contact your veterinarian at the first sign of illness or a flare-up.

Feline Viral Rhinotracheitis Treatment 

Your veterinarian will examine your cat and may test for FHV-1 or related issues to reach a diagnosis. Feline viral rhinotracheitis treatment usually includes:

• Supportive care: fluids, nutrition support
• Eye lubrication and ulcer treatment
• Pain medication or anti-inflammatories for discomfort
• Antivirals (such as famciclovir)
• Antibiotics if a secondary bacterial infection is present
• Appetite stimulants if needed
• Follow-up visits to protect vision and prevent chronic issues

Long‑Term Management for Chronic or Recurring FVR

If your cat shows constant signs or has frequent flare-ups, these steps can help:

• Stay current on feline viral rhinotracheitis vaccine boosters
• Manage stress through routine, enrichment, gentle handling, pheromones
• Feed a consistent, balanced diet; ask your vet about omega-3 supplements
• Identify and manage stress triggers like boarding, noise, new pets, or routine changes
• Discuss prophylactic or periodic antivirals with your vet if flares are frequent
• Avoid immunosuppressive medications unless your vet recommends them

Managing FVR Flares at Home

If your cat is having a flare, take these steps immediately while contact your veterinarian.

• Encourage drinking with multiple water stations
• Add water to wet food to boost moisture
• Warm wet food slightly to increase aroma
• Offer small meals and hand-feed to encourage eating
• Run a humidifier or spend time in a steamy bathroom to ease congestion
• Wipe nose and eye discharge with warm saline on a damp cotton pad (one wipe per eye)
• Toss each used cotton pad and use a fresh one for the next cleaning
• Never give human cold medicine or leftover antibiotics to your cat
• If your cat isn’t eating or drinking for more than 24 hours, or has trouble breathing, contact your nearest pet ER

Keeping your feline viral rhinotracheitis kitty healthy is all about recognizing the signs to watch for, taking effective precautions, and working in close partnership with your veterinary care team. With improved care, modern solutions, and early intervention, you can protect your cats and keep your home happy and healthy.
