With the shift to allowing pets in shelters, it becomes a little more clear, IMO, that people should obey mandatory evacuations. I live 2 miles away from a nuclear power plant, so I'm mindful of the (hopefully low) possibility of needing to do so. But, the reason it's not 100% clear is if you have a situation like I do. I have several feral cats that live indoors. However, I think I have a workable intermediate solution where I'd catch who I could, then open the windows for the ferals to "self-evacuate" and try to re-trap them later. (The ferals live indoors as I'm on a busy street and would prefer they not get turned into rugs.)
