This one I believe was done by the same (unknown) person as the puma watercolor I have listed, but there's definitely a different sort of immediacy to it, with these bared fangs open at us! But, though I think portraying a wild cat, I love how much it might just be a drawing of the house cat in a particularly feral mood.
Paper size 9 3/4" x 6 3/4". Graphite on watercolor paper. Very good condition, blank on reverse.
