Upper respiratory infections (URIs) in cats can cause a range of symptoms, and the severity of symptoms can vary depending on the underlying cause and the individual cat.
We’ll take a look at some causes of upper respiratory infections. We’ll also discuss symptoms you should keep an eye out for.
Viral and Bacterial Infections
Feline herpesvirus (FHV-1) and feline calicivirus (FCV) are the two most common viruses that can cause URIs in cats. These viruses are highly contagious and can be spread through direct contact with infected cats, contaminated objects, or the air.
Bacterial infections, such as Bordetella, Chlamydophila, and Mycoplasma, can also cause URIs in cats. These infections can be secondary to a viral infection or can occur on their own.
Environmental Factors and Stress Cause URIs
Poor air quality, exposure to second-hand smoke, and high levels of dust or other irritants can irritate a cat’s respiratory system and lead to a URI.
Also, stress can weaken a cat’s immune system, making them more susceptible to URIs. Stressful situations can include moving to a new home, changes in routine, or the introduction of a new pet or family member.
Genetics can also play a role.
7 Symptoms of Feline Upper Respiratory Infections
- Sneezing: Sneezing is one of the most common symptoms of URIs in cats and is a sign that the cat’s respiratory system is trying to clear out irritants or infections.
- Runny nose: A runny nose, or nasal discharge, can be a sign of a URI in cats. The discharge may be clear, cloudy, or yellowish in color.
- Eye discharge: URI’s can also cause eye discharge, which may be clear, cloudy, or yellowish. The discharge may be accompanied by redness, swelling, or squinting in the affected eye.
- Coughing: Some cats with URIs may develop a persistent cough, which can be a sign of irritation or inflammation in the respiratory system.
- Loss of appetite: Cats with URIs may experience a loss of appetite, as the discomfort and inflammation in the respiratory system can make eating and breathing difficult.
- Fatigue: Cats with URIs may become lethargic or have reduced energy levels, as the infection can be taxing on the body.
- Fever: Some cats with URIs may develop a fever, which is a sign that the body is trying to fight off the infection.

It is important to seek veterinary care if you suspect your cat has a URI, as these infections can become serious if left untreated.
Your veterinarian can diagnose the underlying cause of the URI and provide appropriate treatment to help your cat recover. In some cases, antibiotics or antiviral medications may be necessary to clear the infection.
