I am sorry to hear of your loss. I understand how sad it can be, I lost my 20 year old cat, Kaysee, on January 4, 2000.
I thought I saw her around the house many times after that. The latest event happened just this week. Kaysee liked to play with balled up socks. If I left a drawer open even a tiny bit, she would pull the socks out and play with them.
Well the other day when my son and I arrived home, there was a balled up sock in the middle of the living room floor. We looked at each other and both said Kaysee!
