Hi Sorcha! I'm surprised it's taken me this long to read your postings here. I'm so happy for you, dear lady, that you had "visits." That's wonderful.
My cat (one before my present one) came back to me the first night that she passed. Again, it was just to let me know she was fine and not to be upset. I found it helped so much.
Sending my best and so glad you shared what happened, --SunnySister
