Cibo sources may differ and change depending on the season and geographical area, when large prey animali are scarce Lupi will prey on mice, Rabbits and squirrels, these smaller prey do not provide a substantial part of the wolf's diet but supplement it when larger prey are scarce.

Beavers play an important roll as an alternative Cibo fonte in the summer months, in some areas 60% of the wolf's diet is beaver.

One of the most odd part of the diet of Lupi is fish! Biologist Bod Bromley once observed a lupo in Canada's Northwest Territories catch five pesce in fifteen minuti in the Talston River.
