It is a challenging stretch of days at Dr. K's Exotic Animal ER. Dr. K wrestles a pot-bellied pig, and handles an aggressive squirrel. Dr. T treats a tiny chameleon and a newborn quail hatchling. And, the whole team fights to save a tortoise with a mysterious illness that has her whole shell and body turning white.

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.
