Trivia: In the cartoon's opening title card, there is a tin of cat food with "Farren's Finest" on the label. This is a reference to the assistant animator, Jack Farren.
Continuity mistake: When Sylvester opens the final cupboard door and finds tins of food in it, you can see that he is holding on to the door at the end of the shot, but as the shot changes he now has his arm by his side.
