The Mouse Comes to Dinner (1945)

The popular cartoon cat and mouse are thrown into a feature film. The story has the twosome trying to help an orphan girl who is being berated and exploited by a greedy guardian.

Jasper is given an ultimatum by his master: break one more thing and you're out. Rodent Jerry does his best to make sure that his tormentor "gets the boot".

Tom, complete with mortarboard, is teaching a kitten the basics: "cats chase mice." But Jerry keeps subverting this lesson at every opportunity.

Tom subjects Jerry to his usual harassment; but the cat finds a new enemy, and the mouse finds a new friend, in the canary of the house.

The family dog warns Tom not to make any noise so he can take a nap. Jerry hears this and immediately devises plans to ensure that the dog's nap will be interrupted.

Jerry and his diapered little mouse friend flood the kitchen, then use the freezer to turn it into a skating rink. Even though Tom finds a pair of ice skates, the mice have no problem outmaneuvering him.

Professor Jerry teaches a course in how to outwit cats, but his pupil seems to know more than Jerry.

Tom and Jerry are in a bowling alley. Both spend a lot of time sliding on the well-polished lanes. Eventually, Jerry takes up residence among the pins and Tom tries to bowl him down.

A moment after a bottle of white shoe polish pours on Jerry, Tom hears on the radio that a white mouse, having swallowed an explosive, has escaped from an experimental laboratory and that slightest jar of the mouse could cause it to explode and blow up the entire city. It is then that Tom notices now-white Jerry and concludes it's the escapee.

Tom is given the task of guarding the fridge during the night by Mammy-Two-Shoes, but as soon as he has started he is tricked by Jerry into falling into the basement, where he lands in a barrel of cider. Now drunk, Tom staggers around in the house getting up to no good with Jerry.
