A Boy and a Girl with a cat and an eel
Around 1635
Judith Leyster

"He who plays with cats gets scratched” or as the Parlor Players would say "don't trouble trouble and trouble won't trouble you"

I find this painting very funny.

The National Gallery in London suggests it was painted as a warning against mischievous behavior. Dutch painters at this time commonly used children in allegory for the foolish behaviors of adults.
