Sleeping cat 

"Sleeping Cat" is a simple yet striking graphite drawing by Friedrich Wilhelm Hirt, currently housed at the Städel Museum. Hirt captures the feline form with loose, expressive strokes, focusing on the cat's curled-up pose and the texture of its fur. This intimate study of a sleeping cat exemplifies Hirt's interest in observing and rendering the natural world with sensitivity and detail, a common theme in animal art.
