Update

After Mama Hungry spent the whole night in the ER (no available beds upstairs!) because of fever, the news is good:  the cat scan shows that she had developed an abscess which the doctors will hopefully be able to take care of today without full surgery.  She is on numerous medications and will probably be in the hospital for a few more days at least.  The doctors are optimistic for a full recovery.  Thank you for all of your support and well-wishes.
