For smaller animals such as dogs and cats, government pounds sometimes help evacuate and temporarily house pets for those who have lost their homes. The reality is government pounds clear shelters by killing pets to make room for others. However, when we try to warn people that there's a real possibility that their pets are in danger of being killed, they get angry at me. In fact so many disasters leave beloved pets unclaimed and at the fate of pounds that are run by health departments, which are pressured to kill "excess" animals. Their job is animal care and control of dead animals and diseases or to impound any stray animal and kill it, i.e., management by death.
So it's up to the community and those of us who want to help those in need to reach out and offer aid to local shelters such as finding fosters, providing items like pet food, kennels, fencing, shavings, hay, grains, chicken coops, etc. In addition, after a period of time, unclaimed pets will need homes, and there is a very small period of time to find adopters if the owner does not claim the pet. What people need to know is that California has enacted the Hayden Act, which stipulates a four to six day hold for unclaimed pets (seven days with holiday) at government pounds.
