PIG ON BOARD: Potbellied pigs are some of the more unusual animals Felter has transported.
With about 6 million dogs and cats entering animal shelters in the United States each year, overcrowding has become a serious problem. When space runs out, shelters may be forced to euthanize, or humanely kill, some animals. In fact, about 600,000 shelter animals were euthanized in 2025 alone.
Rescue groups can try to relocate animals to shelters with more space, but these facilities may be far away. That’s when the groups call Race for Life Rescue, a nonprofit based in Tennessee that specializes in transporting at-risk shelter animals all over the country by airplane. Keith Felter is one of the organization’s pilots. He flies a special plane designed to carry animals of all shapes and sizes.
Since 2021, Felter and his crew have relocated more than 10,000 pets—including dogs, cats, potbellied pigs, chinchillas, and rabbits—to shelters where they have better chances of being adopted. Recently, Science World spoke with Felter about his animal rescue flights.
