I haven't figured out the whole idea in this picture by Agostino Carracci. A print is at the British Museum:
The museum says of the picture:
The 'Satyr Mason'; a naked woman lying on a bed with a satyr standing in front of her holding a plumb-line over her; a child also seated on the bed and a cat below it, with a birdcage hanging in the window. c.1590-1595
In case you missed the cat, here is that detail.
The cat looks happy, sitting on a book. That big paw is part of a bed post.
MORE of his work is here.
