Is when cats celebrate their heritage by telling the story of how their cat ancestors revolted against the Seleucid Empire of the 2nd century BCE. The holiday is also observed for about eight days due to the amount of catnip that lasted with-in the "meoworah".

It's a holiday representing cats ultimate win over the dog/cat wars.
Bro 1: Dude bro did you see Elmer celebrating "Catanukkah" he was totally reminiscing his feline ancestry.
Bro 2: Its just an excuse for that fucking cat to by more catnip...

Man I just really wish I could have been part of the chosen feline race, you gotta love those silly hats-on-cats.
