I didn't vote, as the polls were to stringent in their choices...my answer would depend on the situation at hand and the time frame in which I was given to respond.
As bad as it sounds....I'd take my kid, dogs, and cats and the fish would have to fend for themselves. I'd have no where to put them with 2 dogs, 2 cats (pet carrier), a kid, and what belongings/food I could grab and throw in the car.
I know I'm responsible for them, since I brought them home, but I'm more responsible for my kid. The dogs are pretty much self-loading..as they woudl scramble to get in the car as soon as the door opened so they'd be no problem, but if the cats fought going in the pet carrier over a reasonable amount of time (and I was in a real big hurry..say the natural disaster was coming in the next 10-30 minutes) they'd get left too.
I also would not put his safety in jeopardy to save my animals. I can replace them..I can't replace him.
I would, however, not die for any of my animals, that would be fruitless, irresponsible, and selfish of me..considering I have a child (not to mention relatives) that would be left behind without a mother, he also can't replace me.
Although, if I was warned with 1-5 days in advance (like with Katrina) then yeah, of course, all my animals would be evacuated.
