Light-hearted, but serious 
Since she disappeared 8 months ago I have not had to:
-Cover the worktops, fridge and cupboards with sellotape every night to prevent her sleeping all over them. No cats on worktops.
-Remove all traces of water droplets from around sink - she would lap them. No cats on worktops!
-Keep bathroom door closed so she didn't sleep in the sink/bath.
-Be sad about the nose scratches that appeared weekly on my other cats.
-Close doors to stop her sleeping on the baby.
-Open doors slowly, leading with a foot to stop her rushing through, upstairs and under the bed so that I get to lie flat, wriggle under and drag her out shouting and squirming.
-Tape cardboard and old bits of carpet to the lower half of all the doors I had to close because she scratched and destroyed them.
-Close all windows, even upstairs because she could and would get through them so she could get under the bed, or sleep on the baby.
-Discover poo hoards.
Unsurprisingly I got used to not doing these things quite quickly. If she showed up now, I'd be a little cross quite frankly.
Don't worry, at first I was sad and spent weeks coordinating house checks within a 2 miles radius, 3am night walks to call for her and I stuck a picture of her on top of the fridge so I could tell her off.
But, when I think of the additional work she created and what I have saved buying sellotape, I am afraid I just don't want her back. Unreasonable?!
