Yes (raw or undercooked meat of pig, horse, wild boar and carnivorous or omnivorous wild mammals or reptiles)... 

Mammal, fish, and fowl livers are the richest food sources of preformed vitamin A because of the special role of the liver in the uptake, storage, and controlled release of dietary preformed and biosynthesized vitamin A. The liver has an unusually large storage capacity polar bear and seal livers, eaten even in relatively small quantities, were the food source causing acute toxicity in Arctic explorers early in the century, and fish liver oils, such as cod liver oil fed to infants, have not infrequently been the source that caused toxic symptoms (Bauemfeind, 1980). Toxicity has been reported from the daily feeding of chicken liver to infants (Mahoney et al.y 1980). The concentration of vitamin A in other fleshy tissues is considerably less, yet fleshy foods provide a significant portion of the usual preformed vitamin A intake of omnivores and carnivores. 

The carotenoid cleavage enzyme activity is found widely distributed throughout the vertebrates. In a study of a variety of species, enzyme activity was observed in the intestinal mucosa of several mammals, the chicken, the tortoise, and a freshwater fish but was absent from cat intestinal tissue (Lakshmanan et al., 1972). The herbivores examined (the guinea pig and the rabbit) had the highest activities, the omnivores (the chicken, tortoise, and fish) had intermediate activities, and the only carnivore studied, the cat, had none at all. It was pointed out by these authors that it is known that cats become vitamin A deficient...
