It's a wild day at Dr. K's clinic as a malnourished three-month-old lemur rushes in barely breathing and in shock and Stuart, a beloved mouse, get a much-needed eyelift. A good Samaritan rushes in with a wild Muscovy duck that was shot by a neighbor. Dr. K examines the duck and finds that the bullet went into his wing, breaking the wing and that the bird will likely never be able to fly.
