The diet of red fox (Vulpes vulpes) cubs living in a moor in Hungary was studied by scat analysis (n = 77) during the rearing period. The main food source of foxes consisted of small mammals (preferred Microtus voles) which was supplemented with brown hare and gamebirds rarely. Cubs ate remains of carrions (domestic animals, ungulates and carnivores) and invertebrates frequently but in low quantity. The food consisted of characteristically terrestrial, occasionally aquatic and rarely arboreal prey.
