The problem, as I see it, came in the initial stages, when no one was allowed to take their animals because of the frenetic nature of the evacuations. Pets were ripped from the arms of children, and dogs which could have sat in a lap were left behind.
A few days later, animals were regularly taken out with evacuees.
I understand the exigencies of these situations, but pet owners were appalled at the arbitrariness of the evacuation decisions.
Obviously, this can be worked out, as we are witnessing in Texas and have witnessed in NO. Perhaps just the mere threat of such legislation will be enough to force local officials to form some kind of policy that will allow evacuees to at least take their small domestic pets.
I hope you are right that it is left to the local officials. I love my dog and have zero problem with them saving as many animals as possible given the situation. A one size fits all federal mandate designed mostly to grab headlines seems like a real bad way to hadle things.
Stay well.
