I often get up to stretch and relax a bit.  When I do so I usually go
looking for the cat to say hello.  Its hard to stop because I don't
even realise what I'm doing.  Its funny but I've noticed that she is
often part of my thoughts even when I'm doing something irrelevant.
If I'm going to make a sudden move, I automatically consider where she
is so I can avoid her.  When I hear a noise, I wonder if its her.
When I make a noise, I wonder if I've attracted her attention.

Cats were the perfect animal for Schroedinger to use to illustrate
uncertainty.  Unless observed, cats do not occupy any single point.
They probabilistically occupy an entire space.  They move about unseen
and unheard, so once you turn your attention from them, your mind
automatically fills the light cone (or rather, "cat cone") expanding
from their last known position with the possibility of cat.  (And yet,
many people believe that quantum effects are simply impossible for the
human mind to actually grasp.  Never lived with a cat I guess.)

Thus, living with her was like living in a sea of catness just aside
my vision.  It is a very subtle feeling, but it is distinct.  Now,
sometimes I feel it and some times I do not, but either case is
equally terrible.
