Cat FIV: Living Well with Feline Immunodeficiency Virus

FIV-positive cats can live long and healthy lives with appropriate management. Understanding transmission and disease progression prevents unnecessary euthanasia.

Key Facts

FIV is transmitted primarily through deep bite wounds, not casual contact
FIV-positive cats living indoors without bite risk rarely transmit to other cats
Most FIV-positive cats live normal lifespans with appropriate veterinary monitoring
FIV suppresses immune response, increasing vulnerability to secondary infections
An FIV vaccine exists in some countries but has limited cross-protection

Welfare Considerations

FIV-positive cats are frequently euthanised unnecessarily at shelters due to misunderstanding of disease transmission and prognosis. A positive FIV status does not mean imminent illness or death — many cats remain asymptomatic for years. Indoor housing prevents transmission and reduces exposure to opportunistic pathogens. When infections do occur, they should be treated aggressively as FIV cats may not clear them without intervention. Annual monitoring including blood count and protein levels helps detect disease progression early.

What You Can Do

Consider adopting an FIV-positive cat knowing most live long healthy lives
Keep FIV-positive cats indoors or in enclosed gardens to prevent bite transmission
Maintain a twice-yearly vet check schedule with blood monitoring
Treat any infection promptly and follow through with full antibiotic courses
Educate other pet owners that FIV is not a death sentence and casual contact is safe
