By Day She Made Herself Into a Cat by Arthur Rackham

Don’t pet this kitty! There’s something special about black cats, and this illustration for The Fairy Tales of the Brothers Grimm, about a witch who turns into a black cat and glowers at the world, is one of my favourites. I love the robust and expressive pen and ink technique, and the way the cat simply radiates power and anger.

Child with Cat by Pierre-Auguste Renoir

The painting shows Julie Manet, the daughter of fellow artists Edouard Manet and Berthe Morisot, and her kitten who seems to be so blissed out in her lap it’s practically smiling. Children can be thoughtlessly cruel, so I assume that Julie was a nice kid to earn this kind of absolute trust from a cat.
