The film is set in a hotel which has a strict policy against the presence of pets. However, the respective owners of Tweety, Sylvester, and Hector have sneaked them inside, and the trio start chasing each other. Through an attempt of the doorman to evict Sylvester and Hector (the two of the three he saw (off-screen)) through an intercom announcement, it is revealed that numerous pets were already living in the hotel in defiance of its policy.
Plot
Two elderly ladies (one of which is Granny), the owners of Sylvester and Tweety, sneak their pets into a hotel where no pets are allowed. Sylvester, hearing Tweety's singing in the room next to his, writes a letter to the canary from his "Ardent Admirer". Tweety shortly discovers who his "admirer" is, and a chase ensues, which is cut short by the doorman, forcing both Tweety and Sylvester to run back into their rooms and the latter to disguise himself as a lady in bed screaming for help, which causes the doorman to apologize and flee.
Sylvester then sneaks into Tweety's room and tries to get him in his cage; this backfires and he is knocked out by the spring-loaded cage and is dragged back to his room by Tweety. Sylvester then phones Tweety that his owner has a surprise for him; Tweety goes downstairs to receive it, but instead goes down Sylvester's throat, before returning alive with a mouse from the time of Thomas Jefferson. The chase then goes outside, and into the room of Hector the Bulldog.
Sylvester doesn't realize until after he has captured Tweety again that the dog is there. Another chase ensues, involving the dog, cat, and bird, which is also cut short by the doorman, forcing the three to form a truce long enough to disguise themselves as an angry old lady with Tweety's head. The chase resumes again with the three animals running from room to room, making the doorman suspicious. Finally, the doorman (off-screen) sees Sylvester and Hector running, prompting him to finally head back to the lobby and make an announcement over the intercom evicting all pets. However, while it happens, it is revealed that numerous pets, along with several wild animals such as lions and even an elephant, were already living in the hotel, and they all come stampeding over him while running out of the hotel.
Getting up, the doorman dizzily says Tweety's catch phrase: "I tawt I taw a putty tat!" Tweety, popping out of hiding, delivers the final punchline by replying, "You did! You did! You taw a putty tat, a moo-moo tow, a big dowiwwa, a diddy-up hortey, and a wittle monkey!" (A busker's monkey was the last animal to run over the doorman).
