Dr. T must figure out what is causing an extremely swollen foot on Athena the skinny guinea pig. Athena's foot might have to be amputated to prevent the spread of infection. Dr. K performs emergency surgery on a fragile baby bird who can't breathe, and a wobbly hedgehog turns into a medical mystery.

There's never a dull moment at Dr. K's Exotic Animal ER -- A snapping turtle case stumps Dr. K as it takes a mysterious turn, a traveling hedgehog gives Dr. T the silent treatment, a feisty pygmy goat stirs up some mischief, a Quaker parrot arrives without a beak, a bearded dragon needs a warm bath and a pet rat gets a new pair of boots!

Dr. K's clinic fills up with mysterious cases, including a one-year-old sugar glider who is lethargic and isn't eating, a gassy rabbit who worries Dr. K, and a baby macaw who suffers fainting spells. A sassy prairie dog has a toothache and Dr. K finds that she has food and blood stuck in her teeth. If she doesn't address this quickly, Sassy could have a serious problem.
