These are my dogs Frankie, he’s 2 and Roxy, she’s 6! They are outside all the time and we have woods behind the house. They never get fleas or ticks or anything else! Very happy with this product.
Sneezing, coughing, and nasal discharge can indicate a respiratory infection, particularly when several cats live together. Some infections are mild, but others can become serious without proper veterinary care.
Bordetella in Cats is a bacterial respiratory infection caused by Bordetella bronchiseptica. Cats of any age can develop the infection, but young kittens and those with compromised immune defenses are more vulnerable to serious health complications.
What Is Bordetella in Cats?
Bordetella bronchiseptica is a bacterial pathogen that can infect a cat’s respiratory system, particularly the nose, throat, and airways.
The infection is sometimes associated with feline upper respiratory disease and may occur alongside other respiratory pathogens.
Cats living in shelters, boarding facilities, or crowded multi-cat households may have increased exposure.
How Does Bordetella Spread Between Cats?
Bordetella in Cats spreads mainly through respiratory droplets and close contact with infected animals.
Common transmission routes include:
- Sneezing or coughing near another cat
- Direct contact with infected respiratory secretions
- Sharing contaminated food or water bowls
- Contact with contaminated bedding or equipment
- Close interaction in crowded environments
The bacteria can also infect dogs, so infected dogs and cats can still expose each other.
What Are the Symptoms of Bordetella in Cats?
Symptoms vary depending on the cat's age, overall health, and infection severity.
Common signs include:
- Frequent sneezing
- Coughing
- Nasal discharge
- Watery or irritated eyes
- Fever
- Reduced appetite
- Lethargy
- Noisy breathing
In more serious cases, especially among young kittens, the infection may progress to pneumonia.
Seek urgent veterinary attention if your cat develops difficulty breathing, rapid breathing at rest, or severe weakness.
How Is Bordetella Diagnosed?
Veterinarians evaluate symptoms, medical history, and possible exposure to infected animals.
When necessary, they may collect respiratory samples for PCR testing or bacterial culture.
Because several infections can cause similar symptoms, additional testing may help distinguish Bordetella from feline herpesvirus, calicivirus, and other respiratory pathogens.
How Is Bordetella in Cats Treated?
Treatment depends on the infection's severity and the cat's overall condition.
Treatment depends on the infection's severity and the cat's overall condition.
Veterinary care for Bordetella in Cats may include:
- Antibiotics when clinically appropriate
- Supportive care to maintain hydration
- Nutritional assistance if appetite decreases
- Cleaning nasal and eye discharge
- Hospitalization for severe respiratory complications
Veterinarians may prescribe doxycycline when indicated, but they should determine medication selection and treatment duration.
Never give your cat human cough medicines or leftover antibiotics without veterinary advice.
Can Indoor Cats Get Bordetella?
Yes. Indoor cats can become infected when they come into contact with an infected animal brought into the household.
Introducing a newly adopted cat or allowing contact with an infected pet may increase transmission risk.
Monitor cats in multi-pet households carefully when one animal develops respiratory symptoms.

How Can Bordetella Be Prevented?
Reducing exposure to infected animals is one of the most effective ways to prevent Bordetella in Cats.
Helpful precautions include:
- Keeping sick cats separated from healthy pets.
- Washing hands after handling an infected animal
- Cleaning food bowls, bedding, and shared surfaces
- Avoiding overcrowded environments
- Introducing new cats gradually after health assessment
- Reducing stress in multi-cat households
A Bordetella vaccine is available in some regions, but veterinarians do not routinely recommend it for every cat. Veterinarians may consider it for cats at higher risk of exposure.
When Should You See a Veterinarian?
Arrange a veterinary examination if your cat develops persistent coughing, frequent sneezing, fever, reduced appetite, or worsening respiratory symptoms.
Kittens and cats with existing health problems may require closer monitoring because respiratory infections can become serious more quickly.
