Is it possible for a gerbil to die from not eating for the past two days?

In some cases a Gerbil who's is food deprived could potentially began to eat its own hands, tail feet or other cage mates such as younger/weaker gerbils. Sometimes even there own feces. Depending on how your gerbil eats, whether frequent or a little, can determine there reaction. For example some gerbils will just began to drink in the place of food.
