My sympathies PK - I am sure that he was very special to you. I hope the sadness passes & good memories remain.
My little old cat lived to be 20. I was pretty lucky as outside of arthritis & special diet - she still rulled the roost.

She died quietly. I am very attached to my little pekinese - when you live alone , pets are very special company. She is such a delight. Thank goodness she is only 3.
