Not long after our beloved Teddy died ( pack of dogs) I had a half awake/ half asleep sensation of him while my head was on my pillow. I could feel his warmth, and softness, and could even smell his fur. It was such a vivid experience and so calming. I took it as a sign that he was OK, and I really needed that.
Little Cathy will always be with you, Laz. You gave her more love than most cats get, and she knew it. I hope that knowledge comforts you.
You remind me that I can still feel my Rocket sleeping on my hip as he did when he was still corporeal.
I sleep on my side, and he used to climb up on my (rather substantial) hip to sleep with me.
It is very comforting to feel him there each night. He is a good boy.
