My point is --- evacuated by who and evacuated how and evacuated to where?
Those questions could not be answered for any city of any size in concerns of the human population.
You have to make the connection between removing the animals from one location and transporting them to the "safe" location.
Flooding covers huge areas, hurricanes and tropical storms cover huge areas. It's not a matter of grabbing a dog and moving it across the street. The "rescue" may have to come from miles and miles away, closed highways, blocked streets, abandoned cars, debri in the roadway. You have to understand this is not as simple as you would like to beleave.
Been through Betsy, Andrew, Katrina, Rita, and Gustav. I was envolved in the rescue efforts associated with the aftermath of Katrina. Inorder to rescue some one or something you have to have a DESTINATION for the evacuee. You can't leave them on the side of the road. Do you want to know how many flat tires you can expect to have when traveling 60 miles of interstate highway clogged with debri? The answer is if you only got one spare you ain't going to make it. You better have patch kits plus compressor.
You got to walk the mile before you can judge.
