[1] The show features a hillbilly cat, called Punkin' Puss (voiced by Allan Melvin), who lives in a house in the woods of the southern US.
[2] In many cartoons, one of Mushmouse's cousins visits and gives Punkin' Puss a hard time.
They are similar to a hillbilly Tom and Jerry chase series.
The episode "Small Change" has Punkin' Puss (and later, a dog, as well) shrinking to mouse-size.
Note: This episode was, eventually, removed from circulation, as it showed drug abuse.
