🐱 LET’S TALK ABOUT FELINE HERPES (FHV-1)!
Because there seems to be a lot of misunderstanding surrounding feline herpes, especially when it comes to breeders and multicat households.
Feline herpesvirus, also known as FHV-1 or feline viral rhinotracheitis, is extremely common in cats. Once a cat becomes infected, the virus can remain latent in the body for life.
That does NOT mean the cat is constantly sick.
Many cats carrying FHV-1 live completely normal, healthy lives without showing symptoms. Stress can sometimes reactivate the virus and cause temporary symptoms such as sneezing, watery eyes, conjunctivitis, or nasal discharge. Moving, going to a cat show, having kittens, surgery, illness, or other stressful situations can potentially trigger shedding or symptoms.
And this is why I am VERY cautious when I see a breeder advertising their entire cattery as completely “feline herpes free.”
FHV-1 can remain latent without symptoms or active shedding, meaning testing at one particular moment does not necessarily prove a cat has never been infected. Claiming an entire multicat breeding environment is definitively and permanently FHV-1 free is an extremely difficult claim to substantiate.
Personally, I would much rather see breeders EDUCATE and be transparent about these things than make unrealistic absolute claims.
💉 And yes, this is part of what we vaccinate for!
The “R” in the FVRCP vaccine stands for feline viral rhinotracheitis, which is caused by feline herpesvirus.
Vaccination does not completely prevent infection, latency, shedding, or transmission. What it does is help reduce the severity of disease and clinical symptoms. This is one reason vaccination is so important, particularly in multicat environments.
Having been exposed to or carrying FHV-1 does NOT automatically mean a cat is unhealthy or should be removed from a breeding program.
There IS, however, an important distinction.
A healthy cat that occasionally experiences mild symptoms during significant stress is very different from a cat that is chronically symptomatic, constantly sneezing, repeatedly developing significant eye or respiratory problems, or struggling with severe recurring disease.
Those cats deserve further veterinary investigation, and breeders absolutely should consider chronic or unusually severe disease when making breeding decisions. We should be breeding toward overall health, strong immune function, resilience, temperament, structure, and longevity.
There is a BIG difference between:
A healthy cat carrying a common latent virus
and
A cat suffering from persistent or severe clinical disease.
Responsible breeding isn’t about pretending common infectious organisms don’t exist. It’s about understanding them, vaccinating appropriately, practicing good biosecurity, recognizing actual disease, being transparent, and making thoughtful breeding decisions based on the health of the cats in front of us.
EDUCATION over fear. TRANSPARENCY over unrealistic claims. 🖤🐾
