Sir Isac Newton, a wellknown English physicst and mathematician, cut an opening in the bottom of a door in his house so his cat could pass in and out at will. When the cat had kittens, Newton made a smaller hole next to the original one.
But I think I won't do the same thing as Newton did since lots of Mudreg's friends are good at stealing my fish for dinner and make a massive devastation of the fine food table. Not only are they easy in and out at will but also stealing my meal at will.
:-D
