Feline leukemia (FeLV) is a disease caused by a retrovirus, and will result in the suppression of the immune system. When the virus affects kittens, the disease will be severe, as they have a weak immune system. For this reason, the prognosis in kittens with FeLV is poor.
Amnesty (from the Greek á¼Î¼Î½Î·ÏÏÎ¯Î± amnestia, forgetfulness) is defined as:  A pardon extended by the government to a group or class of persons, usually for a political offense; the act of a sovereign power officially forgiving certain classes of persons who are subject to trial but have not yet been convicted.
An amnesty is an official forgetting (the word has the same root as amnesia) of actions against the state by a class of people. An amnesty can come with certain requirements. For example, Ford made amnesty available to men who refused to serve in Vietnam, but required community service.
