I would never leave my pets behind. I would do whatever it takes to have them with me. I have enough carriers appropiatly set up near their cages & by the door and have an emergancy bag in my car as well as one in my house near the door.

Of course it does depened on the situation.
Like if my house was on fire and I couldn't get to my animals in time, but I certainly would try.

If it was due to a storm or something else where I have notice to evacuate then of course they would all come with me, even if I had to live in my vehicle or something.

If it some sort of emergency that only gave me a tiny bit of notice I do have to say that I would rescue the dogs first, the cats, the ferrets, my hamster then my fish, in that order. It is hard to explain why, it's not really that I have favorites I love them all. I guess its a combination of things like who is easier to catch & transport, who is more human like, who is more bonded to me, who would be less stressed if we were to up & move without the comforts of home, the fact that a tiny dwarf hamster would probably die faster (less suffering) in most cases, etc... etc...

Life or death situation then yes I would leave them behind IF I HAD to (fire or something). But the choice to stay in a non pet hotel or the like or on the street you bet I'd be camped out on the street.
