Holistic treatments can help improve the quality of life for cats with Feline Leukemia Virus (FeLV). There is no cure for FeLV, but cats with feline leukemia can live many years without symptoms. Feline Leukemia Virus (FeLV) is a cancer-causing retrovirus that compromises a cat’s immune system. It is a highly contagious virus that is spread through a cat’s saliva, milk, urine, feces or nasal secretions. Feline leukemia symptoms in the early stages can include loss of appetite, weight loss, fever, mouth inflammation, repeated urinary or respiratory infections. Cats with FeLV can live for years before they develop leukemia or lymphoma caused by the virus. The goal of FeLV holistic treatment is to provide ongoing immune support before the cat becomes symptomatic.
