Read the complete plot breakdown of Garfield’s Thanksgiving (1989), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.
Garfield checks the calendar one morning and discovers that he has an appointment with the vet that day. When he erases the date hoping to make Jon Arbuckle forget, he notices that tomorrow is Thanksgiving and instantly demands that Jon Arbuckle buy the food for Thanksgiving dinner. Jon agrees, but takes Garfield to the vet on the way home from the supermarket, which makes Garfield panic.
At the clinic, Dr. Liz Wilson examines Garfield, while Jon tries to talk her into going out on a date with him. She reports that Garfield is “healthy as a horse” but, out of concern for his weight, is putting the cat on a strict diet, to Garfield’s dismay. Jon, flustered, threatens to suffocate his way through the rest of the visit until Liz agrees to the date. When Garfield and Jon simultaneously faint, an exasperated Liz agrees to the date, and Jon invites her to his house for Thanksgiving dinner.
Back home, Jon is excited that Liz is coming over, but Garfield is absolutely miserable at being put on a diet. After picking at half a leaf of lettuce for lunch, Garfield tries to raid the refrigerator but is prevented by Odie, whom Jon has assigned to make sure the cat doesn’t cheat. Later, Garfield weighs himself on a talking weight scale and destroys it for comparing him to Orson Welles, and he’s repeatedly foiled by Odie when he tries to steal cookies, flour, salt and sugar. Garfield then wonders if the lack of food is making him hallucinate.
The next morning, Garfield is even grumpier than usual, but Jon pays him no mind as he begins preparing the Thanksgiving meal. However, Jon doesn’t have a clue on how to cook such a dinner; he forgets to thaw the turkey or leave enough time to thoroughly cook it and thus tries to compensate by raising the oven’s temperature from 325 to 500 degrees Fahrenheit, ignores the stuffing, when told to “rub skin with butter” rubs it on his own skin, and throws all the vegetables in a pile in water on the stove (to which Garfield attempts to sabotage the vegetables by adding garlic powder). Jon shaves and picks a suit, just in time for Liz to arrive and notice he’s not wearing pants. As Jon leaves to check on the meal, Liz spends some time with Garfield, casually listing some of the symptoms of excess dieting, some of which he experiences (like irritability and fatigue) and others he obviously fakes (such as dementia and twitches). She concludes that since Garfield is otherwise healthy, he instead may only need some light exercise, and Garfield kisses her in delight.
In the kitchen, Jon is faced with a still frozen turkey and admits defeat in his attempt to cook dinner. Garfield manages to convince Jon to call Grandma, who arrives seconds later and shoos Jon out of the kitchen. As Jon distracts Liz by giving her a history lesson about Thanksgiving (and Liz dozes off), Grandma proceeds to cook the meal: she cuts the still-frozen turkey into slices with a chainsaw, adds white sauce then batters and deep fries the slices into croquettes, after which she prepares sweet potatoes by covering them with butter, brown sugar and marshmallows, finishing with “split-second cranberry sauce” (from the can) and pumpkin pie. Once everything is ready, Grandma tells Garfield that Liz couldn’t have found a better man than Jon and that she’d better not blow it, then asks Garfield to eat a piece of pie for her as she leaves.
Garfield tells Jon and Liz that everything is ready, and they all proceed into the dining room to eat. Liz declares that it was a wonderful meal and agrees to come back next year, then thanks Jon for inviting her with a kiss on the cheek. Once Liz leaves, Jon, Garfield and Odie declare it was a great day and they’re thankful for Grandma. They decide to head out for a walk to work off the meal, but Odie is too bloated from overeating to get off the couch. Jon immediately puts Odie on a diet, and Garfield assumes the persona of a drill sergeant and gleefully torments Odie into doing push-ups as payback for yesterday.
