Veterinarian Jill Heatley, an associate professor at Texas A&M University's College of Veterinary Medicine and Biomedical Sciences, is treating animals affected by an oil spill near Galveston, Texas. Dr. Heatley explains that the process of cleaning oiled animals can be long and arduous, but it's very important to be meticulous. "Many times, these steps have to be repeated over and over if there is a lot of oil present," Dr. Heatley says. But she says the rescue teams are committed: "We stay as long as we're needed."
