Ain't She Tweet (1952)

Continuity mistake: At the beginning of the cartoon, you can see that the top part of Tweety's cage is small but in the next shot has increased in size.

Continuity mistake: When Sylvester is looking at Tweety Pie in the pet shop window, you can see the cage next to Tweety's cage is much further away, but a couple of seconds later it is now next to Tweety.

Continuity mistake: Throughout the cartoon, the position of the "Beware of Dogs" sign on the wall at Granny's house keeps changing between shots. On at least one occasion, the sign is missing.

Trivia: When Sylvester picks up a brick and says "Laugh this off!", there is a building beside him which says "I. Wyner Co." - a reference to the Warner Brothers background artist Irv Wyner.
