Mr. Sanders

Mr. Sanders is the landlord and owner of Westboro Apartments. Because of her wild personality, Francine occasionally gets in trouble with him.

In "Francine Goes to War," he tells Francine to stop drumming on the roof at sunrise because they had been getting complaints from a new tenant.

In "Feeling Flush," he replaces the toilet lid Francine and Catherine broke. When Francine checks the water-usage meter for her apartment, he becomes suspicious that her family is using more than their fair share of water.

Appearance
In his first appearance, Mr. Sanders was a dog depicted wearing a yellow shirt, blue overalls, and brown shoes, and carries tools around his waist.

However, he was completely redesigned in "Feeling Flush". In his appearance, he was a cat. He wore a turquoise vest and white undershirt with a blue tie. He also wore jeans and carried a set of keys, most likely to all of the rooms in the complex.
