As I am relatively new to cats, I have yet to lose one. However, my RB dog Rat has visited several times. There is a full length mirror on the front of an old wardrobe in our living room. Several times I have walked past the mirror and saw Rat following behind me, as she constantly used to do. I have also heard her tags clinking, a sweet jingle jangle that was hers and hers alone. I am always heartened when she makes an appearance. I wish she would stop by more frequently but I feel sure she is quite busy with her buddies in heaven and does us a great favor by fitting us in her tight schedule on occasion.
