Cat's Cradle

From a prompt from Well For The Journey

The first one -
the big Tuxedo -
decided that his proper place
was on her right,
pushing me off the left edge
of the bed.
The second,
now on a bigger bed,
chose the midline
as his domian.
The third -
having no other choice -
enveloped her head,
like a feline halo;
and I realized
that my pledge
of eternal adoration
was now 
in second place.
