FeLV / FIV Testing for Cats
in Vero Beach, FL
Important screening for cats in Vero Beach, Florida
Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are two serious viral infections that affect cats
While they are very different diseases, both can impact a cat’s immune system and long-term health. At Mermaid SANDS, we offer FeLV/FIV testing for cats as part of a focused care model that supports cats and families throughout Vero Beach and Indian River County.
What are FeLV and FIV?
FeLV (Feline Leukemia Virus) and FIV (Feline Immunodeficiency Virus) are viruses that weaken a cat’s immune system, making it harder to fight off infections.
- FeLV is most commonly spread through close, prolonged contact, such as grooming or shared food and water bowls
- FIV is most often spread through bite wounds, particularly during fights
Some cats may live for years without obvious symptoms, while others can become ill much sooner.
A note about “feline AIDS”
You may hear FIV referred to as “feline AIDS”. This term is used because FIV affects a cat’s immune system in a way that is similar in concept to how HIV affects people.
However, it’s important to understand:
- FIV is a cat-only virus and cannot infect people or other animals
- Many cats with FIV live long, comfortable lives with proper care
- A positive FIV test is not an emergency diagnosis
The term can sound alarming, but it does not mean a cat is immediately sick or suffering. Testing helps guide thoughtful, informed care—not panic.
Why FeLV/FIV testing matters
Testing allows us to:
- Identify infected cats early
- Reduce the spread to other cats
- Make informed decisions about care, housing, and long-term health
Cats can carry these viruses without showing signs of illness, especially in the early stages.
“But my cat stays indoors…”
This is a very common and understandable thought—and testing is still important.
Even indoor cats may be exposed through:
- Prior unknown exposure before adoption
- Brief escapes outside
- Contact with other cats in the household
- Bite wounds that went unnoticed
Many cats who test positive were previously thought to be “low risk.” Screening helps remove guesswork.
A note about kittens and test results
In young kittens, FeLV or FIV test results can sometimes be misleading.
Kittens may test positive due to maternal antibodies passed from their mother, especially for FIV. This does not necessarily mean the kitten is truly infected.
Because of this:
- A positive test in a young kitten should be interpreted with caution
- Retesting at an appropriate age is recommended to determine true infection status
- Many kittens who initially test positive will later test negative once maternal antibodies fade
Follow-up testing helps ensure accurate diagnosis and avoids unnecessary worry.
Why these tests don’t always turn positive right away
FeLV and FIV also have a window period.
After exposure:
- It can take weeks to months before a test becomes positive
- A cat may be infected but still test negative early on
- There may be no outward signs of illness during this time
Testing provides a snapshot in time, which is why repeat testing may be recommended based on age, exposure risk, and history.
How FeLV/FIV testing works
FeLV/FIV testing is done with a simple blood test that screens for both viruses at the same time.
The test:
- Requires only a small blood sample
- Provides reliable initial screening results
- Helps guide next steps in care
Testing is commonly recommended for:
- Kittens and newly adopted cats
- Cats with unknown history
- Cats undergoing certain procedures
- Cats who may be exposed to other cats
How FeLV/FIV testing works at Mermaid SANDS
Mermaid SANDS focuses on high-impact primary procedures, such as spay, neuter, and dental cleanings.
For that reason, FeLV/FIV testing is offered as an add-on service for cats already scheduled for a primary procedure. This allows us to provide important screening while maintaining an efficient and sustainable care model.
FeLV/FIV testing is not offered as standalone appointments at this time.
Is this service a good fit for my cat?
FeLV/FIV testing may be added to your cat’s visit if they:
- Are already scheduled for a primary procedure
- Are healthy enough for routine blood testing
Eligibility is reviewed during scheduling to ensure testing is appropriate.

What to expect at your cat’s visit
When FeLV/FIV testing is added to a scheduled procedure:
- A small blood sample is collected
- Results are reviewed by veterinary staff
- Findings are documented for your records
If a test result is positive or unclear, your primary veterinarian can guide you through confirmatory testing and appropriate follow-up.
Taking the next step
If your cat is scheduled for a spay, neuter, or dental procedure, FeLV/FIV testing can be added to their visit.
