Given the question: Generate a question about the following movie plot: Interviewing leaders of animal organizations and volunteers who went to New Orleans after Hurricane Katrina, it is revealed that at the beginning, everyone had different ideas about how things should be done, but no one was willing to take charge because the problem was bigger than anyone could have imagined. The film champions the volunteers whose only concern was saving animals, unlike the animal organizations who were more concerned with the chain of command.After about a month, the state put the Louisiana Society for the Prevention of Cruelty to Animals in charge who told the volunteers to stop rescuing. Anyone not with the LA/SPCA was considered rogue and operating outside the authority. Meanwhile, the police in St. Bernard Parish were shooting dogs in what they say was a form of mercy.Months after Katrina, many owners are still not reunited with their pets because they do not know where they are and do not have the means to find them. Some people have found that their animals have been adopted out and cannot get them back.The film ends with Barkus, a Louisiana pet parade, indicating New Orleans was not washed away with the hurricane.
The answer is:
What was the only concern of the volunteers?
