Dr. K treats a young male monkey with anger issues and a cuddly guinea pig with a large lump under its chin. Additionally, she discovers a mystery mass in a beloved pet rat, and a noisy pig gets a pedicure.

There is no such thing as a boring day at Dr. Susan Kelleher's South Florida exotic animal emergency room, where she and her staff treat every animal that will fit through the door, from big cats to hedgehogs, birds, reptiles, rabbits and every other animal imaginable — everything but a dog or house cat! Dr. K's team treats unusual and heartwarming cases every day.

Dr. K's clinic is full of unusual cases, including a sugar glider mother-daughter duo with a slew of unexpected issues. Meanwhile, Dr. K treats a tortoise with a suspicious growth on its shell and examines a one-month-old baby guinea pig.
