🐾 FIV in Cats – What Every Cat Owner Should Know 🐾
Feline Immunodeficiency Virus (FIV) is a common infectious disease in cats that affects the immune system, making infected cats more vulnerable to illness over time. While an FIV-positive diagnosis can be worrying, many cats live long, happy lives with proper care and monitoring.
🦠 How is FIV spread?
FIV is most commonly spread through deep bite wounds from infected cats. Unneutered male cats that roam and fight are at the highest risk. Casual contact such as sharing food bowls, sleeping together, or grooming carries a much lower risk of transmission.
What happens after infection?
FIV infection usually progresses in stages:
Acute Phase:
Shortly after infection, cats may develop mild fever, swollen lymph nodes, poor appetite, or lethargy, although many show few or no obvious signs.
Asymptomatic (Silent) Phase:
This stage can last months or even years, with cats appearing healthy while the virus slowly affects the immune system.
Progressive Phase:
As immunity weakens, some cats become more prone to recurring infections and illness. Common problems include:
• Severe dental disease and gingivitis/stomatitis
• Skin, eye, respiratory, or urinary infections
• Weight loss
• Neurological changes or seizures
• Increased risk of certain cancers
How is FIV diagnosed?
Diagnosis is usually made with a simple blood test at your veterinary clinic. Additional testing may sometimes be recommended.
Caring for an FIV-positive cat
There is no cure for FIV, but good management can make a huge difference.
✔ Keep cats indoors to reduce disease exposure and prevent spread to other cats
✔ Feed a high-quality balanced diet
✔ Avoid raw food diets
✔ Schedule regular veterinary check-ups and blood tests
✔ Monitor for changes in appetite, weight, behaviour, or signs of illness
✔ Treat infections promptly
✂Spaying and neutering help reduce roaming and fighting behaviour, limiting the spread of the virus.
The good news?
Many FIV-positive cats enjoy excellent quality of life and can live normal life spans with proper care.
If you have questions about FIV testing, prevention, or caring for an FIV-positive cat, speak with your veterinarian — early diagnosis and ongoing management are key. 🐾
