Jill, I am afraid, gave her a lot of worry over this duty of the expulsion of aliens, for Jill would sooner play with an alien than expel it, and her plan was to gambol up to the intruder with misplaced welcome. It is true that the effect was just the same, because a trespassing cat, seeing an alert fox-terrier rapidly approaching, seldom, if ever, stops to play, so that Jill’s method was really quite effective, too. But Puss-cat had high moral purpose behind her: she wanted not only to expel, but to appal and injure, and like many moralists of our own species, she enjoyed her fulminations and onslaughts quite tremendously. She liked punishing other cats, because she was right and they were wrong, and vigorous kicks and bites would help them perhaps to understand that. But though Puss-cat resembled her mother in the matter of the high sense of duty and moral qualities, she had what Martha lacked: that indefinable attraction which we call charm, and a great heart. She was always pleased and affectionate, and went about her duties with as near an approach to a smile as is possible for the gravest species of animal. Martha, for instance, played with Jill as a part of her duty, Puss-cat made a pleasure out of it and played with the ecstatic abandon of a child. Indeed, I have known her put dinner a quarter of an hour later, because she was in the lovely jungle of long grass at the end of the garden, and was preparing to give Jill an awful fright. This business of the jungle deserves mention, not because it was so remarkable in itself, but because it was so wonderful to Puss-cat.
