It really depends on the situation,
Like say the house catche's fire one night and everyone is woken up by the fire alarm...I would set the animal's loose so they could get out on their own or find shelter somewhere, the person in question run's out of the house and I grab a loved plant on the way.
In any emergency, if I remember correctly...if at all possible set all pet's loose so that they have a chance to get out (like rat's/snake's just open the cage).
But true I agree with everyone here, I would save a person!
I believe that all knowledge, the totality of all questions and answers, is contained in animals.
