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.
The amnesty is usually established for a fixed period of time and may be related to outstanding tax debts of one or more annual periods. If the taxpayer fails to cancel the debt by taking advantage of the amnesty, and then the evasion is discovered, severe punishment and sanctions apply.
