I could be lying

I could be lying When I am crying I could be telling tails Out of school Playing fast With the rules I could be, I could be But what are the odds That I'm a fraud? Well, that's a twist You'll have to risk If you want To be close to me And you'd better be ready For an aroma quite heady Coming from my poop and from my pee I'll lick my fur And I'll purr As I scratch your furniture 'Cause I'm a cat, I'm a brat (Some say twat, so there's that) And you'll never Ever Own me.
