As a cat owner, you’re likely familiar with the term "cat flu," but did you know there’s more to this common condition than you might think?

Here are four key facts about cat flu that could help you better care for your feline friend.

1. Cat Flu Isn’t Caused by a Single Type of “Bug”

The term "cat flu" refers to a collection of upper respiratory illness symptoms suffered by affected cats, rather than one specific disease.

The illness can be caused by several different viruses and bacteria, with most cases (80%) linked to two main culprits: feline calicivirus and feline herpesvirus.

Most cats with cat flu will develop symptoms of sneezing, with watery eyes and nasal discharge, and sometimes also a fever.

If a secondary bacterial infection develops (on top of the initial viral infection), the pet’s eye and nose discharge may become thicker and “snotty”.

Cats infected with feline herpesvirus may also develop eye ulcers, whilst cats with calicivirus may develop tongue ulcers.

2. Cat Flu Can Stay in Your Cat’s System Long-term

Unfortunately, once a cat is infected with feline herpesvirus or calicivirus, the virus may remain in their system for life.

Some cats may experience recurring symptoms, particularly in times of stress or with ongoing mouth inflammation.

3. Vaccination Doesn’t Prevent Cat Flu, but It Helps

The good news? Whilst vaccinations won’t fully prevent cat flu, they can significantly reduce the severity of symptoms if your cat is exposed to these viruses.

For cats affected by the recent vaccine shortages, Tricat F3 vaccinations are now available, although other types of cat vaccines are still on back order.

Keeping your cat up to date on their vaccines remains an important step in supporting their health.

4. Treatment is Largely Supportive

Unfortunately, there is no cure for cat flu, but supportive care can make a big difference in helping your cat recover.

Treatment focuses on managing symptoms and preventing complications such as severe eye ulcers or pneumonia.

Depending on the case, your vet may recommend antibiotics, eye ointments, hydration support, pain relievers, appetite stimulants, or even antiviral medications for more severe or recurrent cases.
