OMC - What Did They Put On Me?

So, the people were out doing some shopping, and I was having a nice peaceful rest.  When they came home, they told me they had a surprise for me.  Catnip, I hoped.  Or maybe a nice crunchy sounding mouse.  All of mine are too far under the couches for my little arms to reach.

They said this surprise would help me since I don't have much chur (you know, chub and fur) and I'm always snuggling into blankets to keep warm.  That sounded great!  I wondered what it could be.

Little did I know that the surprise was going to be an instrument of torture.   As soon as I saw it, I started running.  The maid/mommy held me down and put it over my head.  I, of course, put up a good fight.  She somehow got it on me anyway.  It was terrible!  How could anyone do this to any kitty they supposedly love?

When she turned me loose I rolled and wiggled and tried to push it off.  I was successful in getting it off of me pretty quickly, but she put it right back on.  I started slinking around the house like I was fighting this thing that was wrapped around me.  But then I realized, this doesn't feel too bad.  In fact, it's kind of warm and cozy.  It's like being wrapped in a blanket and still being able to walk around.

Wow!  This must be the greatest invention ever.  A blanket that moves with you...  I wonder what it's called?
