King-Size Canary.

An alley cat searches for food in some garbage cans late at night. He sneaks onto the property only to wake a sleeping bulldog. The cat is about to eat him because he has already seen the cartoon they are in and that he winds up saving the cat's life later. After a quick run around the block, the cat and a canary wind up back outside of the house, where a now gigantic bulldog appears before them. The now giant-sized cat chases the slightly smaller canary through the side of the property.
