If you’ve recently heard your cat has tested positive for Feline Immunodeficiency Virus (FIV), take a deep breath—you’re not alone, and your cat can still live a long, happy life.

At Grace Animal Hospital, we believe that understanding your pet’s health is the first step in giving them the best care possible. Let’s break down what FIV is, how it’s diagnosed, and what it means for your cat moving forward.

What Is FIV?

FIV stands for Feline Immunodeficiency Virus, a virus that affects a cat’s immune system—similar in concept to HIV in humans. Over time, it can weaken your cat’s ability to fight off infections.

The important thing to know?
Many cats with FIV live long, normal lives, especially with proper care.

There is often a long period where cats show no symptoms at all, and our goal is to keep them healthy during this time for as long as possible.

How Is FIV Diagnosed?

FIV is typically discovered through a simple blood test performed during a routine vet visit.

Initial screening tests detect antibodies
Positive results are often confirmed with additional testing (like PCR or Western Blot)
Kittens under 6 months may test positive temporarily due to their mother’s antibodies

That’s why follow-up testing is so important—especially for young cats.

How Do Cats Get FIV?

The most common way FIV spreads is through deep bite wounds, usually from fights between cats.

Other key points:

Casual contact (sharing bowls, grooming, snuggling) is very unlikely to spread FIV
Transmission from mother to kitten is rare
It is not contagious to humans

What Happens If My Cat Tests Positive?

An FIV diagnosis doesn’t mean your cat can’t thrive—it just means we need to be more intentional about their care.

1. Keep Your Cat Indoors

This helps:

Prevent spreading the virus to other cats
Protect your cat from additional infections

Indoor living is one of the most important steps in managing FIV.

2. Focus on High-Quality Nutrition

Avoid raw diets, as they can expose your cat to bacteria and parasites that a weakened immune system may struggle to handle.

Stick with trusted, balanced commercial diets.

3. Stay on Top of Preventative Care

FIV-positive cats need:

Regular parasite prevention
Routine wellness exams (ideally twice a year)
Annual bloodwork to monitor overall health

Even small changes—like weight loss or low energy—should be checked promptly.

4. Be Thoughtful About Vaccinations

Vaccination plans may vary depending on your cat’s lifestyle:

Indoor-only cats may not need all vaccines
Outdoor or exposed cats may still require them

We’ll help tailor a plan specifically for your pet.

5. Monitor for Changes

Because FIV affects the immune system, early detection of illness is key.

Watch for:

Weight loss
Decreased appetite
Changes in behavior
Signs of infection

Catching issues early can make a big difference.

Can FIV Be Treated?

There’s no cure for FIV, but supportive care can go a long way.

Some treatments may include:

Managing infections quickly
Immune-support strategies (with veterinary guidance)
In certain cases, antiviral medications for specific symptoms

The focus is always on quality of life and prevention.

Living With an FIV-Positive Cat

Here’s the good news:
FIV-positive cats can live full, happy lives—often alongside other cats in the home, as long as they are not aggressive.

With proper care, many pet owners find that their FIV-positive cats are just as loving, playful, and joyful as any other.
