Overpopulation of feral animals (cats, dogs, rabbits, etc.) or stray animals (goats, camels, cows, etc.) is a serious global problem that affects the community, environment, and public health. Since most of stray animals do not depend on humans for food and shelter, and therefore, can reproduce and increase uncontrollably.  These may lead to road traffic accidents, and possible interaction with people, especially children, and may cause injuries through bites and scratches and may transmit zoonotic diseases.

ETS use trained personnel and adopt humane methods to capture the animal (which may include traps which do not harm the animal) and impound the animal.
