Mr. Z leaves food and water for the cat in the kitchen, then opens the roof window and leaves the house.
He knows very well, because he has seen it, that when the house has been quiet for a while and the roof window has been left open, the neighborhood cats that do not have an owner will come in to steal food from his Mixed-Tree. His Mixed-Tree also knows this very well, and that is why, when she is left alone, she waits, ready, right on the terrace windowsill to protect her territory and her food. The stray cats are much hungrier than she is and will take much greater risks (they may show their claws and scratch) to get in to finish the four remaining rampoines.
Mr. Z is already fine with this situation. Once, he found a mouse on the terrace, and his Mixed-Tree didn't pay attention. She is not a hunter. If there are cats around the terrace, if they want to get in and fight with the Mixeta (she is then forced to put up a fight), the mice won't come near. The more cats want to get into the house, the more furious the Mixeta will be, and the further away the mice will stay. Mr. Z, to foment this war, leaves canned food (not biscuits) for the Mixeta. No cat can resist. He knows that no mouse will get in through the window if there are one or two cats peeking around.
Mr. Z would be sincerely sorry if one day he found the Mixeta badly injured on the windowsill. But until that moment arrives, he goes to work peacefully. And if Mr. Z creates this little avoidable chaos for his own interests, how come we are surprised that country A sells weapons to country B in the hope that B, armed with the weapons, will want to attack country C, which will, in turn, cause country D, which is the real objective of all this, to reap the rewards?
