Dr. K starts this challenging day with Chloe, a 6-year-old guinea pig who is having a seizure. A catheter is inserted to get fluids and medications into the guinea pig. Dr. K then moves on to Jed, a ferret who was once bright and active, but now has a fever and is completely lethargic. Dr. K thinks he may have perforated his intestine, but it is even worse than she feared. Suddenly a cockatiel arrives, bleeding from the mouth. Dr. Diaz rushes her to the surgery room, with Dr. K close behind. At the end of the day, Dr. Thielen must help a woman say goodbye to a cherished pet.
