I, Kitty Senior, enjoy my life as a house cat. When it is time to eat, my humans are there to serve me food. When it is time for play, my humans are there with toys. And when it is time to sleep, I have my very own human heater waiting for me in my futon; his name is Dear, A.K.A. Undies Man (don't ask, humans are weird). All is purrfect. Well, all was perfect... until Nekomaki decided to bring a little demon "cat" called Acorn into the house. I'm not even convinced that this ball of snotty fur even is a cat. I can already tell: my twelve years on this earth is NOT going to be peaceful...
