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.

This series provides a platform for the many members of the comedic Wayans family. Popular recurring sketches include Homey D. Clown, the Homeboy Shopping Network, Men on Film and Great Moments in Black History.

"It's the end of the world as we know it (and I feel fine)," sang R.E.M.'s Michael Stipe, and it's a proclamation that must resonate with the people profiled in this series. That's because they are all preparing for doomsday, whether it's caused by a natural disaster, a financial collapse or a nuclear winter, and their plan is to outlast and outlive any apocalyptic scenario. The series goes inside America's "prepping" subculture and introduces otherwise ordinary folks who are stockpiling food, water, weapons and whatever else they think is necessary in the event basic services should falter and society turns chaotic and violent. Also, each prepper's plan is reviewed by the consulting firm Practical Preppers, which analyzes its potential effectiveness in case the prepper's worst fears become reality.

As one of the lead designers for nine seasons on ABC's Emmy-winning "Extreme Makeover: Home Edition," Paul DiMeo encountered his share of next-to-impossible construction projects. So building wilderness retreats is a walk in the park by comparison, right? Not so fast. Paulie, as he is known, and master fabricator Pat "Tuffy" Bakaitis are partners in a cabin design and construction business called Cabin Kings, and in "Building Wild," the duo create unbelievable rustic getaways, transforming discarded materials into eye-catching contraptions and overcoming outrageous building challenges along the way. In each episode, Paulie and Tuffy provide the big ideas and construction know-how to a client looking to build a backwoods paradise on a challenging property. To keep costs low, the landowners supply some materials, bring together a workforce of friends and family and agree to do the entire build in one week.

Extreme survivalists go head to head in a race across the Alaska wild. Using ingenuity, experience and just the gear they can carry in their packs, the participants have 60 hours to reach the finish point of each leg of the adventure -- the series features 13 legs -- and in addition to navigating treacherous glaciated river valleys, barren ridgelines, and high mountain peaks, the challengers battle hunger, dangerous predators and unpredictable weather. There is no grand prize awaiting each leg's winner, other than the pride of accomplishing a grueling feat. For season three, the 12 competitors are divided equally into four teams -- Military, Endurance, Alaskans and Lower 48.
