There is no denying that our pets become a permanent part of our families. When our little boy died, our 2 dogs grieved almost as much as we did, and to this day if I mention Isaacs' name, they will start looking for him.
And someday I will grieve over their passing too.......they are truly a mans best friend.
So sorry to hear of your familys loss, and I also believe that God will send you comfort in your time of mourning.
