Rat often is cityscape 1-4 or the last server on the list snowscape. He will ONLY poo (he calls it biting) if you threaten to poo, bite, scratch, ect., he will do it first. In the snowscape he nests under a garbage pail or in the barn. In the cityscapes he nests only under a garbage pail but he likes the barn more than ANY of those garbage pails. He flies a bit if absolutely necessary he usually acts out climbing by flying up. He climbs up to the barn window or climbs up a garbage pail. He usually makes it only half done because he doesn't want to lay an egg.
