This study investigated optimal sample types to identify FeLV-infected cats and predictors of long-term survival in a cohort of FeLV-positive cats followed for up to 8 years after diagnosis.
A large Italian study found that FeLV-positive cats had a median survival of about 714 days (just under two years), compared to nearly 11 years for cats without retroviral infections.

cat diagnosed with Feline Leukemia Virus (FeLV) unfortunately has a variable life expectancy, with the median survival time after diagnosis ranging from 2.5 to 3 years. However, many cats can live shorter or longer, depending on various factors.

Such details provide a deeper understanding and appreciation for Feline Leukemia Virus Life Expectancy Study.
Prognosis for cats with progressive infections is variable depending upon current immune status, stress, or concurrent disease. Some progressive cats may remain nonclinical for several years.

As we can see from the illustration, Feline Leukemia Virus Life Expectancy Study has many fascinating aspects to explore.
This retrospective study investigated survival times and effects of selected predictor factors on survival time in a population of owned pet cats in Northern Italy testing positive for the presence of FIV antibodies and FeLV antigen.
