This week in the Blue Cross Hospital Grimsby, care assistant Debbie takes delivery of a very precious package, as a box of abandoned kittens arrive at the clinic; meanwhile vet Natasha and nurse Natalie are in surgery, neutering a couple of Chihuahua pups. In London, ambulance driver Sonia collects long term patient 15-year-old Bichon Frise Mitch, who urgently needs to see vet Aysha.
