Kawai has a particular gift for painting animals and many of his compositions are filled from top to bottom with flamingos, foxes, owls, ammonites, and pelicans. Cats seem to be his favorite and they are pictured as conquerors, tyrants, and gods—in one of his pictures a feisty cat has killed an angel like it was a songbird and is holding the limp corpse in his fangs while standing like a stylite atop a classical column.
