Sleeping Girl With a Cat, Pierre-Auguste Renoir, 1880, 120 x 94 cm, oil\ on canvas. Image credit here.
Renoir also included cats in several paintings, perhaps the best-known being Girl with a Cat. Renoir's cats were always pleasant, contented felines. To share their warmth, he often nursed one of the many cats that lived around his house. Occasionally, the Institute Pasteur in Paris, checking the authenticity of Renoir's paintings, has found cat hairs in the paint, which helps date the paintings.
Both the girl and the cat are the epitome of contentment. See previous post on Cats in Art here.
