The Docs at Critter Fixer take a trip back to their alma mater to help a cow that's separated from her herd. Plus, Dr. Hodges performs tail surgery on a serval cat that doesn't want to be sedated and enlists help to operate on a chihuahua's damaged eye. While Dr. Ferguson helps a cat whose cough may be a sign of a serious illness, and a family of alpacas come in for parasite and pregnancy checks!
