According to this page at franzmarc.com, Cat Behind A Tree was also called "Children's Picture," and was in the Hanover Museum till 2009, when it was returned to the family of its original owner. Also noted is the unusual composition: the cat, the logical focus of the painting, is partially obscured behind the thick blue (masculine color) tree, sleeping cozily in a yellow (feminine) field. A play between shelter and support? With Marc, that's possible - and here, I have to say it again, delectable.
