Strange but true story. My husband and I had a cat "escape" and never come back - he was old and probably went off to be by himself. When we moved a little neighbor boy kept shuffling his legs and he finally said - what's your cat's name? I said, cat? He said "yes, the gray cat that keeps rubbing my legs".
So........I guess our kitty moved with us even if in spirit form. I told this boy that we did not have a cat and he said oh yes you do and it keeps rubbing my legs - and he would catch it out of the corner of his eye but he thought it just darted off fast before he could see it fully.
