Scaredy Cat (1948)

Continuity mistake: When Sylvester's conscience appears by the tree stump, the position of Sylvester's left leg on the stump changes between shots.

Continuity mistake: When Porky puts Sylvester in the basket in the kitchen, he walks to the door and you can see the door has a handle on it. In the next shot, the handle has disappeared.

Continuity mistake: When Sylvester grabs the tree to fight the mice in the house, the sky in the background is red. But when he runs back to the house, the sky is now dark.

Trivia: This was the first cartoon in which Sylvester is named, as well as the first appearance of Sylvester in a cartoon directed by Chuck Jones.
