this spot is taken

There is a spot in the house that all three cats fight for. It is right next to my mother's bedroom door;  it tends to get extra warm because the boiler is underneath that spot. 90% of the time we can find one of the three cats laying there. What's funny is, they won't move for anything; you can almost step on them and they won't flinch. Brave are we? So I, the great owner that I am, love to lay out on top of them. At first they don't cry, but after a while they yell, "enough is enough!" Haha, they would usually run away and glare at me from a distance, they must be thinking, "Why must you always bother me?". Ah, I love my cats. Abby happens to be my cat, so she gets abused more than Kilala and Momo. She knows I bother her out of love, but due to old age she has gotten grumpier and grumpier; I still love my fat cat.
