Daisy's parents are the mother and father of Daisy Duck. They make their first appearance when Daisy introduces Donald to them in the theatrical cartoon Donald's Diary(1954). Her mother looks like James Whistler's portrait of "Arrangement in Grey and Black", is deaf and uses a hearing accessory. She was voiced by Vivi Janiss. Daisy's father is a photographer with a crazy-looking expression.
Besides Daisy, they have three kids who look exactly like Huey, Dewey and Louie. According to Carl Barks' Flip Decision (1953), Daisy also has a sister living in Duckburg, which means that her parents must have had at least one other daughter.
As of yet, the only other appearance of Daisy's parents was a cameo in The Danger Caves, chapter 12 of the Donald Duck comic sub-series Tamers of Nonhuman Threats. They can be seen in a picture in Daisy's house.
