Learning that your cat may have been exposed to Feline Immunodeficiency Virus (FIV), often referred to as Feline AIDS, can be overwhelming. As a caring pet owner, you want to understand what this means for your furry companion, how to test for it, and what steps to take next. Rest assured, with early detection and proper management, many FIV-positive cats live long, happy lives. Let’s break down what you need to know about testing for FIV and how to ensure your cat stays healthy.

⚠️ What to Watch For

Feline Immunodeficiency Virus is a slow-acting virus that weakens a cat’s immune system over time. Many cats with FIV show no symptoms for years, making it challenging to detect without proper testing. However, there are some signs you can keep an eye out for:

  • Frequent infections (e.g., gum, skin, or respiratory infections)
  • Weight loss or poor appetite
  • Fever that doesn’t go away
  • Swollen lymph nodes
  • Chronic diarrhea
  • Wounds that heal slowly

These symptoms can also indicate other health issues, so testing is essential for a definitive diagnosis.

🔍 Possible Causes

FIV is primarily spread through bite wounds, which is why outdoor or unneutered male cats—who are more likely to engage in territorial fights—are at higher risk. Other, less common transmission methods include:

  • From an FIV-positive mother to her kittens during birth or nursing
  • Through deep scratches
  • Very rarely, through shared food bowls or grooming

FIV is not airborne and cannot be transmitted to humans or other non-feline pets. Indoor cats are at much lower risk of contracting the virus, but testing is still important if your cat has ever been exposed to the outdoors or other cats.

✅ What You Can Do at Home

While you can’t diagnose FIV at home, there are proactive steps you can take to monitor and protect your cat’s health:

  • Schedule regular veterinary checkups to catch any signs early
  • Keep your cat indoors to minimize exposure to other potentially FIV-positive cats
  • Maintain a healthy, balanced diet to support their immune system
  • Ensure your cat is up to date on vaccinations (though some vaccines are not recommended for FIV-positive cats—discuss this with your vet)

Testing is the only way to confirm whether your cat has FIV, so if your cat is showing symptoms or has been in a high-risk situation, consult your vet promptly.

💡 When to Call a Vet

If your cat has been bitten by another cat, shows any of the symptoms listed above, or has been in a high-risk environment (e.g., outdoor access), it’s time to consult a veterinarian. Testing for FIV involves a simple blood test, often referred to as the ELISA (enzyme-linked immunosorbent assay) test. This test detects the presence of FIV antibodies in your cat’s blood.

In some cases, your vet may recommend a follow-up test, such as a Western blot or PCR (polymerase chain reaction) test, to confirm the diagnosis. These additional tests are especially useful for kittens under six months of age, as maternal antibodies can sometimes lead to false positives in younger cats.

Early detection is key. By identifying FIV early, you can take steps to support your cat’s health and reduce the risk of secondary infections.

FAQs

Q: Can FIV-positive cats live with other cats?
A: Yes, but only if they have a non-aggressive relationship. FIV is primarily spread through bites, so cats that groom each other or share food bowls are unlikely to transmit the virus. However, it’s best to discuss your specific situation with a vet.

Q: How often should I test my cat for FIV?
A: Testing is recommended if your cat is exposed to high-risk situations, such as outdoor access or fights with other cats. Otherwise, routine testing may not be necessary unless symptoms develop.

Q: Is there a cure for FIV?
A: Unfortunately, there is no cure for FIV. However, with proper care and regular veterinary monitoring, FIV-positive cats can live normal, healthy lives.
