Macavity's brother is Jeremy James
A very respectable cat.
Macavity's parents are quite upper-class.
Really? Well fancy that.
Macavity's sister is Flossywossyjossykins.
She is terribly ashamed of brother Mackie's 'little sins'.
Macavity's grandma took to her bed
When she heard that his Guardian Pussy had fled.
But Macavity just laughs, for he says that it's sublime
To be known throughout the world as the Napolean of crime.
