The Veterinarian's Adopted Children (1968)

Winnie's mother is going to Bangkok to settle an inheritance matter and is looking for a good boarding house for her child. She calls Dr. Linager, who tells her that he has a boarding house for "expensive children," but the price is no object to Winnie's mother. When Winnie shows up, the good Dr. Linager is a little surprised. He is a veterinarian and thought he was going to be looking after a Siamese cat, but everyone in the house naturally welcomes the charming little Winnie.
