Cold and Windy

It is really cold here in central NY. The coldest this winter. Even with insulation, new windows, and new furnace it is drafty near the walls. The cold seems to roll off them. All the animals are indoors. One of the cats was giving me fits and wouldn't come in. No matter what I tried he had been out for 3 or 4 weeks with out setting foot indoors. He must have finally gotten really tired of the cold. I held open the front door with a block, corralled the dogs in the kitchen and kept everything quiet and he walked himself in. This hadn't worked other times. I'm glad to stop worrying about him. The trick will be to keep him in. The last two times he was in since last April, after a week he wants back out and makes a real fuss. Any ideas?
