The Humane Society of the United States (HSUS) and The American Society for the Prevention of Cruelty to Animals (ASPCA) are two of the many organizations on the ground in Alabama, Mississippi, and Missouri to help lost and injured animals due to the series of tornadoes that hit 14 states on April 27 and 28. The organizations are helping local emergency agencies and humane societies to organize volunteers. In Alabama and Mississipi, HSUS and ASPCA are currently caring for more than 270 displaced animals. In Missouri, the local Humane Society of Missouri has set up an emergency animal shelter that can hold more than 300 animals. The series of tornadoes has been one of the deadliest outbreaks in the United States.
