Understanding Upper Respiratory Infections in Cats at Providence Vet

Upper respiratory infections (URIs) are common in cats, particularly in multi-cat environments such as shelters, catteries, and households with multiple pets. These infections can range from mild to severe, affecting a cat’s overall health, comfort, and quality of life.

At Providence Vet in Virginia Beach, Virginia, we believe that early detection, proper treatment, and prevention strategies are essential to keeping your cat healthy. This guide will help you recognize, manage, and prevent upper respiratory infections in your feline companion.

What Are Upper Respiratory Infections (URIs) in Cats?

Understanding URIs in Cats

A feline upper respiratory infection (URI) is similar to a common cold in humans, though it is caused by different viruses and bacteria. These infections affect the nose, throat, and sinuses, leading to symptoms such as sneezing, congestion, and eye discharge.

The most common causes of feline URIs include:

  • Feline Herpesvirus (FHV-1) – Highly contagious and can lead to lifelong viral shedding.
  • Feline Calicivirus (FCV) – Can cause respiratory symptoms along with painful oral ulcers.
  • Bordetella bronchiseptica – A bacterial infection that worsens respiratory symptoms, particularly in multi-cat settings.

Symptoms of Upper Respiratory Infections in Cats

Mild to Moderate Symptoms

If your cat has a URI, you may notice:

  • Frequent sneezing
  • Coughing or throat irritation
  • Nasal discharge (clear, yellow, or green)
  • Red, watery, or swollen eyes
  • Loss of appetite
  • Congestion or difficulty breathing through the nose

Severe Symptoms Requiring Immediate Care

In some cases, a URI can lead to serious complications. Seek veterinary care if your cat experiences:

  • Open-mouth breathing or wheezing
  • Severe lethargy or refusal to eat
  • High fever (above 103°F)
  • Blue-tinged gums or difficulty breathing (a sign of oxygen deprivation)

If left untreated, URIs can progress to pneumonia or chronic respiratory disease, requiring intensive medical care.

How Do Cats Catch Upper Respiratory Infections?

Common Ways URIs Spread

URIs spread easily between cats, especially in crowded or stressful environments. Common transmission methods include:

  • Direct contact with an infected cat (licking, grooming, or sharing space)
  • Airborne droplets from sneezing or coughing
  • Contaminated objects such as food bowls, bedding, and litter boxes
  • Human transmission through contaminated hands or clothing

High-Risk Factors for URI Development

Some cats are more vulnerable to developing respiratory infections, including:

  • Kittens and senior cats with weaker immune systems
  • Cats in shelters or multi-cat homes where exposure risk is higher
  • Unvaccinated cats, as they lack protection against common URI viruses
  • Stressed or immunocompromised cats, as stress can weaken immune defenses

To reduce your cat’s risk, quarantine new cats for at least 10–14 days before introducing them to your household.

Diagnosing Upper Respiratory Infections at Providence Vet

When to Seek Veterinary Care

While some mild URIs resolve on their own, it is crucial to seek veterinary care if symptoms persist for more than 10 days or if your cat experiences difficulty breathing, extreme lethargy, or loss of appetite.

Schedule an appointment at Providence Vet if you suspect your cat has a URI.

Veterinary Diagnosis and Testing

A veterinarian will evaluate your cat’s symptoms and may perform:

  • Physical examination to assess congestion, fever, and respiratory function
  • Nasal or throat swabs to identify the causative virus or bacteria
  • Bloodwork to check for secondary infections or underlying conditions
  • X-rays if pneumonia or chronic respiratory disease is suspected

Early diagnosis allows for targeted treatment, leading to a faster and smoother recovery.

Treatment Options for Upper Respiratory Infections

Home Care for Mild Cases

Most mild URIs can be managed at home with proper supportive care. Helpful treatments include:

  • Using a humidifier to loosen mucus and improve breathing
  • Encouraging hydration by offering fresh water or wet food
  • Warming food slightly to make it more appealing to cats with congestion
  • Gently wiping nasal and eye discharge with a warm, damp cloth
  • Keeping your cat isolated from other pets until symptoms improve

Veterinary Treatment for Severe Infections

If a URI becomes severe, your veterinarian may recommend:

  • Antibiotics for bacterial infections
  • Antiviral medications to manage herpesvirus symptoms
  • Fluids (IV or subcutaneous) for dehydration
  • Oxygen therapy in cases of significant respiratory distress

In rare cases, hospitalization may be necessary for intensive supportive care.

Preventing Upper Respiratory Infections in Cats

Vaccination Is Key

Vaccines reduce the severity of respiratory infections and help prevent serious complications. Core feline vaccines include:

  • Feline Viral Rhinotracheitis (FHV-1)
  • Feline Calicivirus (FCV)
  • Bordetella vaccine for high-risk cats

Keeping up with regular vaccinations and booster shots is one of the best ways to protect your cat.

Environmental Prevention Strategies

Maintaining a clean, stress-free environment helps prevent the spread of URIs:

  • Provide good ventilation in your home to reduce airborne pathogens
  • Regularly clean litter boxes, food bowls, and bedding
  • Minimize stress by maintaining a consistent routine and offering enrichment
  • Quarantine new cats for at least 10–14 days before introductions

Recognizing URI Emergencies

Seek immediate veterinary attention if your cat exhibits:

  • Severe respiratory distress (wheezing or open-mouth breathing)
  • Extreme lethargy or refusal to eat for more than 24 hours
  • Persistent high fever (above 103°F)
  • Bluish gums or tongue (cyanosis), indicating oxygen deprivation

For additional emergency guidance, refer to the AAHA guide on Respiratory Distress in Pets.

FAQs About Upper Respiratory Infections in Cats

Can humans catch a URI from their cat?
 No, feline URIs do not spread to humans, though good hygiene (washing hands after handling an infected cat) is recommended.

How long does a URI last?
 Mild infections typically last 7–10 days, while severe or chronic cases may persist for several weeks.

Can a cat recover from a URI without treatment?
