The meme is deemed funny or clever because it capitalizes on a punctuation error that drastically changes the meaning of the phrase 'EAT LESS KITTENS.' Without proper punctuation, it seems to suggest eating fewer kittens, but the intended message is probably encouraging voters to 'EAT LESS' and 'KITTENS Vote Republican,' with 'kittens' being an endearing term possibly referring to the voters. The humor comes from this misunderstanding and the cute imagery of kittens dressed in cow costumes, which adds a layer of absurdity.
