Where is food stored for use during the winter hibernation of frogs?

Depends of the animal and the place they are from. Some animals hibernate for ages either underneath loads of earth and fallen leaves, near the main branch under a tree, some even make nests that look look like animated bee hives that they stay in until they feel a small drop of warmth they they emerge from their hiding place and they begin again.

But some animals are meant for the winter and especially husky, ect, that always love a good mess around in the snow.
