Feline Leukemia and Sarcoma Viruses

  • William D. HardyJr.
Part of the Developments in Oncology book series (DION, volume 28)


There are an estimated 40 million pet cats in the United States and approximately 2%, or 1 million cats, are infected with the feline leukemia virus (FeLV) (1). The virus is spread contagiously among pet cats and is the most frequent killer of cats among infectious disease microorganisms (1–4). FeLV causes both proliferative (neoplastic) and degenerative (blastopenic) diseases in cats living in household conditions (2,3). More FeLV-infected pet cats develop degenerative diseases than develop neoplastic diseases (1). Of all the retroviruses, the biology of FeLV has been most completely elucidated.
