Final answer:
Herbert Hoover and Lou Hoover received a Siamese cat from the American consul of Bangkok during his presidency from 1929 to 1933.
Step-by-step explanation:
The president and his wife who received a Siamese cat as a gift from the American consul of Bangkok were Herbert Hoover and Lou Hoover. This took place during Hoover's presidency, which was from 1929 to 1933. Siamese cats were considered rare and exotic pets at the time, and this gift was a symbol of goodwill and friendship between the United States and Thailand, which was historically referred to as Siam and is the origin of the Siamese breed. Herbert Hoover was one of several presidents who had pets while in office, enjoying the companionship and positive public image that came with having a pet.
