Feline leukemia virus is a retrovirus that infects cats. FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved. If the animal's immune system fails to neutralize the virus, it may become severely weakened by it, potentially leading to lethal disease.
