FeLV presents significant management challenges in shelters, with progressive understanding of disease course enabling welfare-focused decisions that avoid unnecessary euthanasia of FeLV-positive cats.
FeLV management welfare has been transformed by improved understanding of the disease course. Cats with regressive infection who clear the virus do not require lifelong management concerns. Cats with progressive infection can often maintain good quality of life for extended periods with appropriate care. Shelter policies that automatically euthanize FeLV-positive cats apply older understanding to a condition where modern testing can distinguish progressors from regressors. Welfare-focused FeLV management prioritizes individual assessment over blanket policy, enabling cats with good prognoses to access adoption.
