In biology, animals are defined as multicellular, eukaryotic organisms, the vast majority of which consume organic material, breathe oxygen, can move, and reproduce sexually. This definition encompasses an incredibly wide range of animals both familiar and unfamiliar, from dogs, cats, horses, and cows to the world of insects and alien-seeming undersea creatures. Whether they are offering companionship, inspiring wonder, providing food, or playing an essential role in the ecological systems we depend on, animals are more than important - it’s impossible to imagine human society without them.

Taking care of our animal partners in society requires a keen understanding of their biology and behavior as well as attention to animal welfare. Animal welfare is typically defined according to “The Five Freedoms”: freedom from hunger and thirst through proper nutrition, freedom from discomfort through the provision of adequate shelter, freedom from pain, injury, and disease, freedom to express normal behavior (e.g. chickens roosting), and freedom from fear and distress.

Everyone loves animals, but if you are especially fascinated by animal behavior and passionate about animal welfare, you can pursue a veterinary career. Veterinarians are responsible for ensuring animals under their care receive adequate nutrition as well as treatment of injuries and disease control, and they must receive a doctorate in veterinary medicine as well as a state license to practice.

These highly educated experts in animal care typically work in private clinics, zoos, or farms, and demand for their services is expected to grow rapidly. According to the Bureau of Labor Statistics, veterinarians earned a median annual salary of $95,460 in 2019.
