I feel this says all that can be said about a cat.
"MY SUMMER IN A GARDEN... Charles Dudley Warner
I hesitate to speak of his capacity for friendship and the affectionateness of his nature, for I know from him his own reserve that he could not care to have it much talked about. We understood each other perfectly, but he never made any fuss about it; when I called his name and snapped my fingers, he came to me; when I returned home at night we was pretty sure to be waiting for me near the gate and would rise and saunter along the walk, as if his being there was purely accidental - so shy was he commonly of showing feeling. There was one thing he never did - he never rushed through an open doorway He never forgot his dignity. If he had asked to have the door opened, and was eager to go out he always went out deliberately; I can see him now, standing on the door step, looking about at the sky as if he was thinking whether it were worth while to take an umbrella, until he was near to having his tail shut in.
(I notice that Candy never rushes out a door one opens for her. Perhaps this is normal for all cats?)
