What is the ruling on leaving parrots alone to die of starvation after their owners travel?

If the two hateful creatures are left with enough food and drink for the intended duration of the journey, then there is no sin in their death. However, it is a precaution to take them along or leave them with someone who can care for them, or to leave them with enough food for a longer period, because a traveler does not know what difficulties he might encounter. A woman entered Hellfire because of a cat she imprisoned until it died, for she neither fed it nor gave it water to drink.
