Moving? What, me?

Dear Diary,
My pets have been busy cleaning the house from top to bottom for the past few weeks, and last week someone came around and measured the rooms.
Now I've heard them talking about selling the house. Does this mean I'm moving? I've just got settled, got brave enough to wander out onto the grass in the dark and meet other cats, and sit outside on the table for hours on my own.
Why are they doing this to me?
