Wait a minute. Cats are noisy as all hell playing chase throughout the night, sliding across the wooden floors, knocking stuff down off the tables, chairs, TV stand, ..opening the kitchen cabinets crying for you to let them in to the bedroom.... And cleanliness, see above, not to mention the shredding of the toilet paper if you happen to forget and put the roll on backwards. Confetti..... But how can you not love them when they sit there looking at you all pathetic when they are caught in the act.
