I'm so sorry for your loss. It's like losing a big part of your heart when a beloved pet passes away. It does get better with time but it never goes away. I firmly believe that God has a place in heaven where our pets wait for us, happy where they are but waiting just the same. Big hugs to you and your family. It was nice that you got to say goodbye.
P.S.
Your baby looked just like two of my cats Mom.
