Produced by the team that created BBC's "Planet Earth" series, "The Hunt" explores the relationship between predators and their prey. Sir David Attenborough narrates this documentary while the cameras follow the animals in their natural habitats. With a specific focus on strategy, the hunters are examined in detail -- from their use of the environment to their sharp instincts and physical prowess. On the other side of the fence are the hunted, which use their senses and defense tactics to flee when they feel threatened. Each episode centers on a different habitat, and the last one focuses on the state of the planet.

From the creators of the real-time law enforcement series "Live PD" comes a version for animal lovers. It captures the fast-paced drama and intensity of a hospital procedural mixed with the unbreakable bonds between pets and their owners. Host Mark Steines ("Entertainment Tonight") is joined by veterinary experts in the studio to guide viewers through each episode, giving commentary on what is seen at featured animal hospitals and mobile vet clinics around the country. Cameras trail teams of emergency veterinarians and specialists as they work tirelessly through the night to save the lives of pets. The series also accompanies on-call vets to homes and farms to treat animals that are too sick or too big to travel.

In the varied forms of veterinary medicine, Dr. Susan Kelleher's practice may be one of the more unusual. Known as Dr. K, she runs South Florida's Broward Avian and Exotics Animal Hospital, and this series follows the staff as it cares for rabbits, ferrets, foxes, fish, birds, reptiles, marsupials, and even primates. As do some other vets, Kelleher thinks domesticating wild animals like monkeys is a bad idea, but that feeling doesn't interfere with her taking care of them: "If it will fit through the door, I'll treat it," she says.
