You may say a cat uses good grammar.
Well, a cat does —
but you let a cat get excited once;
you let a cat get to pulling fur with another cat on a shed, nights,
and you’ll hear grammar that will give you the lockjaw.
Ignorant people think it’s the noise which fighting cats make
that is so aggravating,
but it ain’t so;
it’s the sickening grammar they use.
