The enner beast becomes tired by using its shouts (-1000 stamina).
In addition, shouting makes it hungry (-100 nutrition points - that's 1/10th of a kiwi) and the amount of time it takes (action points - think like Jagged Alliance or XCOM) is reduced by its biting skill.
So technically the enner beast could tire itself out, or starve itself to death.
