Or possibly “the bird is the word”.
Personally I feel that the the bird and the yellow cat are actually friends but it’s tough to tell. Parental guidance suggested, the cats really go at it and the swearing is something awful. Some will wonder why the camera operator didn’t try to intervene. The camera operator (not me) has all his finger and toes and no stitches and didn’t lose any blood. Such would not have been the case if they had tried to stop the fight.
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.
