A "Canadian Medical Association Journal" paper states that "The famine in Cuba during the Special Period was caused by political and economic factors similar to the ones that caused a famine in North Korea in the mid-1990s. Both countries were run by authoritarian regimes that denied ordinary people the food to which they were entitled when the public food distribution collapsed; priority was given to the elite classes and the military." The government did not accept American donations of food, medicines and money until 1993, forcing many Cubans to eat anything they could find. In the Havana zoo, the peacocks, the buffalo and even the rhea were reported to have disappeared during this period. Even domestic cats were reportedly eaten.
