Wildlife rehabilitators must make difficult decisions daily and take their responsibility to each animal seriously. Every animal is carefully evaluated, diagnosed, and treated through a program of veterinary care, proper diet, medication, physical therapy, exercise, and prerelease conditioning. Successful rehabilitation means that released animals are physically and psychologically fit and able to truly function as wild animals. This includes the ability to recognize and obtain the proper foods, select appropriate mates and reproduce, show fear of potential dangers (people, cars, dogs, etc.), and know how to avoid predation. Successful releases are planned according to weather, season, habitat, safety, and location.
