One of the most well-known painters in history, Van Gogh is best remembered for his turbulent life and tragic passing, but little is known about his private affairs. The fact that van Gogh had no pets is one of the few things that is known about him. This is probably because he was always on the go and never stayed there for very long. However, Van Gogh did admit to having a soft spot for animals, especially cats. Van Gogh expressed his regret at not ever having a cat of his own in a letter to his sister.
