Trivia: After Sylvester has swallowed the bowling ball, he goes back down the drainpipe and out into the street. When this happens, look behind him and you can see a sign saying "Drink Friz! Six Delicious Flavors" - a reference to the director Friz Freleng. There is also a building with "Champin's 5 and 10" on it - a reference to the animator Ken Champin.
Continuity mistake: When Sylvester runs into the Broken Arms Apartment Building, you can see the front door of the entrance has nothing on it, but when Sylvester is being attacked by the guard in the next shot, there are metal bars on the door.
