1920s Lingo describing someone (something) who is great, incredible or special. Usually indicating stylishness or innovation. Pajamas were a relatively new fashion in the 1920s. The term "cat" was beginning to be used as a term to describe the out going and unconventional jazz-age flappers.

The term "cat's pajamas" comes from E.B. Katz, an English tailor of the late 1700's and early 1800's, who made the finest silk pajamas for royalty and other wealth patrons. This phrase is often likened to and/or confused with the 20's term "cat's meow".

Slang Used in the 20’s, this expression is very similar to "cool."

Also the name of my kitty rescue. Save the homeless kitties. Adopt now!

Awesome, very good. Apparently coined back in the 1920's, but it is still in use today.
