Thank you for sharing this beautiful memorial with us.
We too also went through a huge loss last summer with the sudden passing of Heff. Heff was also way to young to die.
You need to take comfort in knowing that yes Abby's life her on earth may have been way to short but luckily for Abby each day she did have was with a very loving caring family. Sadly allot of pets on earth can not say that.
I know for us after losing Heff I swore never ever again would I ever own a pet....8 days later in walks Lulu into our life! Lulu is no Heff but I always tell me wife that I am sure she is a reincarnation of Heff in certain ways.
Sorry I wish I could say more to help ease your pain.
