Do lions create bad kamma for their next life when they kill?

In Buddhism, bad Kamma begins with a bad intention. What can we say about animals, let's say a tiger or a lion that kills other living beings by instinct? They don't have the same understanding as we do as human beings and they simply cannot become vegetarians: so are they creating bad Kamma that might ripen in a next life? For instance, if I used to be a lion will I suffer bad Kamma consequences in this human life because I killed and ate living beings?
