The Brown Kitten, the one whose fur was black and yellow mixed so finely as to look brown, had climbed the barn stairs to see them. When he reached their corner he sat down and growled at them. His mother said nothing at first, but when he went so far as to switch his tail in a threatening way, she left her new babies and sprang at him and told him not to show his whiskers upstairs again until he could behave properly.
