Pete usually used his own door except when he could bully me into opening a people door for him, which he preferred. But he would not use his door when there was snow on the ground.
While still a kitten, all fluff and buzzes, Pete had worked out a simple philosophy. I was in charge of quarters, rations, and weather; he was in charge of everything else. But he held me especially responsible for weather. Connecticut winters are good only for Christmas cards; regularly that winter Pete would check his own door, refuse to go out it because of that unpleasant white stuff beyond it (he was no fool), then badger me to open a people door.
He had a fixed conviction that at least one of them must lead into summer weather. Each time this meant that I had to go around with him to each of eleven doors, hold it open while he satisfied himself that it was winter out that way, too, then go on to the next door, while his criticisms of my mismanagement grew more bitter with each disappointment.
Then he would stay indoors until hydraulic pressure utterly forced him outside. When he returned the ice in his pads would sound like little clogs on the wooden floor and he would glare at me and refuse to purr until he had chewed it all out… whereupon he would forgive me until the next time.
But he never gave up his search for the Door into Summer.
