If I read the story correctly, the fire started in two barrels, but then spread to the home. That's all fine and dandy if they want to fight the fire first when it was just in the barrels, but once it hit the house, they needed to get everything living out first before proceeding to fight it.
I agree with you. Like I said, I wasn't there... I don't know any more details then you do as far as why that didn't happen. But do you know any person who has 3 pets who would just let them die in a fire? I'm just saying there has to be a reason that happened, and it's unlikely to me that they thought to themselves "ah, let em roast."
