Hi Dave,
I am an animal lover, and have felt the loss of each my "babies" very deeply.
Our cats are like children to us, they have the run of the house, sleep with this, including under the duvet when it is cold, and so on.
Each loss is a bereavement, and whilst time may diminish the deep anguish, there will still be moments of anguish and pain.
Those who have no animals cannot understand these sentiments, and I believe that I can truly empathise with you.
I offer you these words:
"We do our best homage to our dead when we live our lives most fully, even in the shadow of our loss".
May you find some small comfort from one who understands your grief.
Jon
