The Mystery of the Ubiquitous Cat

My cat, Watson, is a stalker.  Every time I go into a room the cat is lurking somewhere.  She is forever hidden under a dresser, sitting in a bookcase, or hiding behind a curtain.  I got used to her looking at me like this constantly a long time ago.

The thing I can't figure out is how she is in all rooms at the same time.  If I am doing a load of laundry she will be in the closet behind the hamper.  Then she is under my bed when I pass through my bedroom.  When I go through the kitchen she is sitting on the counter and when I get to the basement she is hiding behind the laundry sorter.

How is this possible?!?!

I have decided that either she can either teleport or there are several identical cats inhabiting my house.

I bought a bell for the other cat who never makes any noise so that I can here is she has managed to get trapped in a closet or room and let her out.

I think I will put a bell on Watson as well so I can see if there is more than one cat.  I hope the magic cat clones can't clone the bell as well!
