A security guard refuses to let Granny drive her car back into the mountain cabin because the roads are blocked due to a bad snowstorm, but Granny pleads to be let through because her bird and cat would starve inside the cabin.
Meanwhile, friends Sylvester and Tweety are alone in Granny's mountain cabin. A radio report announces that due to heavy snow the roads will be blocked for six weeks. Sylvester nervously checks the cabin for food but finds nothing but boxes and boxes of bird seed. He tries to talk Tweety into being cooked, first in a sailboat in a kettle on the stove, then ice skating in an oiled frying pan. Meanwhile, a hungry mouse (whom is more desperate for food than Sylvester is) keeps trying to eat Sylvester, and has better luck in eating Sylvester than Sylvester's own attempts in eating Tweety.
Granny finally arrives on snowshoes with a backpack full of food, but it's just more bird seed, much to Sylvester's disappointment. Sylvester munches the bird seed miserably, but the mouse has one last try at eating Sylvester. When Tweety asks Sylvester how he liked the bird seed, the mouse bites him on the tail, Sylvester yells and flies up in the air. Tweety says "Aw, come now, it can't be that bad.", as the cartoon ends.
This cartoon provides an anomaly in the Sylvester & Tweety pairings: In this one, Tweety and Sylvester start off as friends, and it also also a rare cartoon in these Tweety/Sylvester pairings where Sylvester is in the role of a victim instead of being the aggressor; in this case Sylvester attempts to eat Tweety because he would starve, and is also the prey of a crazed mouse whom is desperate for food.
The cartoon was later remade as the Pink Panther short "Pinknic" in 1967.
For reasons unknown, the original ending card was lost when many later prints replaced the end card with a 1959-64 MM end card. When this cartoon was later digitally remastered and restored and released on the Japanese DVD I Love Tweety Vol 2. and Looney Tunes Golden Collection: Volume 2, the original end card was plastered from another cartoon in the 1948-49 or 1952-53 seasons to look like the original end card. For unknown reasons, it is unknown why WB did not do this for "Kit For Cat" on Looney Tunes Golden Collection: Volume 1 as the original end card from this cartoon could have been used for that cartoon.
