It's NEVER "just a cat". Just like it's never "just a son" or "just a mother". These little furry lovies ARE our family. Of course you are upset and concerned; all of us would be, too. We know how you are feeling because we'd react the same way.
Don't worry, we are a very large group and carry a lot of influence as far as prayers and good thoughts go! We are here for you. And for Abby.
(((hugs))) Do keep us posted.
