MAO MAO uprising?

In a fit of old age, I almost forgot that today is Cinco de Mayo.
According to Laurence Simon, though, it’s Cinco de Meow Meow, not Cinco de Mayo. But for his post, I’d have forgotten completely.
Actually, the holiday is a more important date in the United States than in Mexico. (More here.)
Apparently, there’s another version called the Cinco de MAO, but it doesn’t appear to be celebrated much in China.
However, if we consider that the Cinco de Meow Meow is also gaining traction as the Cinco de IMAO, there may be a connection there.
I hate to sound like a leftist whiner, but doesn’t it matter to anyone that May 5 is also Karl Marx’s birthday?? (A fact still remembered in China.)
I could only find one decent picture of Marx which I’d consider fit for feline consumption.

With that, it’s time for me to stop pussyfooting around.
