Cheese Chasers

The cat wakes up, discovers the mice in his mouth, spits them out and, upon hearing them actually begging for him to eat them, feels something is amiss (shown by an imagine spot illustrating the phrase "Something Rotten in the State of Denmark.")

When the mice reject the cheese, Claude questions his sanity, ripping a page out of a mental illness book, folding it into a hat and posing like Napoleon.

Realizing they have to get tough with the cat, the mice corner Claude as he is working on a model ship as a hobby to "help him", and hit him in the foot with a hammer.

[3] The plot resembles that of the 1945 cartoon, Life with Feathers, directed by Friz Freleng and written by Tedd Pierce, which marked the first appearance of Sylvester the Cat in his mature form.

When this cartoon aired on The WB, the part where Hubie and Bertie hit Claude's foot with a hammer in an attempt to be eaten by him was cut.
