The Invisible Mouse

The cat and mouse are involved in the usual chases when Jerry dives into a bottle of invisible ink and discovers that it makes him vanish. Instead of seizing the opportunity to go spy on a girl mouse changing room or something, he uses his new-found invisibility to torment Tom. And it's pretty funny and quite inventive despite being a somewhat one-joke cartoon. And the action never leaves the interior of the house, which is usually the trait of below average T&J shorts. Still worth a 7/10.

However, I'm not sure how an invisible mouse can cast a shadow on the wall, it defies physics and the very nature of being invisible itself.
