Understanding Feline Immunodeficiency and Leukemia Virus — and How to Detect Them at Home

Feline Immunodeficiency Virus (FIV) and Feline Leukemia Virus (FeLV) are two of the most serious infectious diseases affecting cats worldwide. Often silent in their early stages, these viruses can severely compromise a cat’s immune system and overall health if left undetected.

Fortunately, early detection is now more accessible than ever. With home-use diagnostic tools like the TAEING 10-Pack FIV + FeLV Combo Test Kit, cat owners can take an active role in protecting their pets from these life-threatening infections.

What Are FIV and FeLV?

Feline Immunodeficiency Virus (FIV)

FIV is a retrovirus that attacks a cat’s immune system, similar in nature to HIV in humans. It spreads mainly through deep bite wounds, especially during territorial fights among outdoor or unneutered male cats.

While FIV is not necessarily a death sentence, it weakens the immune system over time, making the cat more vulnerable to other infections.

Key facts about FIV:

  • Spread by bite wounds

  • Can remain asymptomatic for years

  • Leads to chronic infections, oral disease, and immune dysfunction

Feline Leukemia Virus (FeLV)

FeLV is another serious retrovirus that can cause immune suppression, anemia, and even cancer in cats. Unlike FIV, FeLV is more easily spread through saliva, nasal secretions, grooming, shared food bowls, and from mother to kitten.

Key facts about FeLV:

  • Spread through close, prolonged contact

  • More contagious than FIV

  • Can lead to lymphoma, chronic illness, and death if untreated

Why Early Detection Matters

Both viruses can be present in a cat's system for months or even years without noticeable symptoms. During this time, the virus continues to suppress the immune system or cause internal damage.

Early detection helps you:

  • Begin supportive care early

  • Protect other cats in the household

  • Monitor disease progression

  • Improve long-term quality of life

About the TAEING FIV + FeLV Combo Test Kit

The TAEING 10-Pack FIV + FeLV Combo Rapid Test Kit is designed for convenient at-home use. It uses lateral flow immunochromatographic assay technology to detect:

  • FIV Antibodies

  • FeLV Antigens

The kit requires a small blood sample (whole blood, serum, or plasma) and delivers results in 5–10 minutes.

What’s Included:

  • 10 test cassettes

  • Sterile disposable droppers

  • Buffer solution

  • Sample collection tools (swabs, etc.)

  • Instruction manual

No additional equipment is required, and the test can be performed in just a few simple steps.

How to Use the Test

  1. Collect a small blood sample from your cat

  2. Mix it with the provided buffer solution

  3. Apply the mixture to the test cassette

  4. Wait 5–10 minutes

  5. Read the results:

    • A visible T line indicates a positive result

    • A C line confirms the test is valid

If the T line appears for either virus, it means the corresponding antibodies or antigens were detected.

Are Home Tests Accurate?

The TAEING test is built to professional diagnostic standards and undergoes strict quality control. However, any positive result should be confirmed by a veterinarian through more specific testing methods, such as:

  • ELISA

  • IFA (Immunofluorescence Assay)

  • PCR (for viral DNA detection)

What to Do if Your Cat Tests Positive

For FIV:

  • Keep the cat indoors to reduce infection risk

  • Monitor for signs of illness

  • Provide a calm, low-stress environment

  • Maintain regular veterinary checkups

For FeLV:

  • Isolate FeLV-positive cats from healthy ones (if fighting or close contact is possible)

  • Monitor closely for anemia or weight loss

  • Provide immune-supportive nutrition and care

  • Schedule regular health evaluations with your vet

While there's no cure for FIV or FeLV, many cats live comfortable and fulfilling lives with proper care and regular monitoring.

Prevention Tips

  • Test all new cats before introducing them to your home

  • Keep cats indoors to reduce contact with unknown or feral cats

  • Spay or neuter cats to reduce territorial fighting

  • Regularly screen high-risk cats with tools like the TAEING combo test

  • Minimize stress and maintain a clean, hygienic environment

Final Thoughts

FIV and FeLV are serious, but manageable, feline viruses. With early detection and the right care, many cats go on to live long, healthy lives.

The TAEING 10-Pack FIV + FeLV Combo Test Kit empowers you to monitor your cat’s health from home—quickly, accurately, and affordably. Whether you’re adopting a new cat, managing a multi-cat household, or simply being proactive, routine testing is one of the best tools you have.

Knowledge is protection—and early action saves lives.
