Continuity mistake: When Sylvester sucks the spaghetti into his mouth after thinking he has captured Tweety, you can see bowl next to him is full of spaghetti, but when he is clobbered on the head by the mallet, the bowl is empty.
Other mistake: In the opening credits, Tom O'Loughlin's surname is spelt as "O'Laughlin."
Continuity mistake: At the beginning of the cartoon, we see a view of Granny and Tweety's hotel balcony and you can see there is nothing in sight, but when Granny enters in the next shot, a table appears from nowhere.
