This time it was Cleo who alerted me that Joanie was under the pavement inside the drain. I quickly jumped into the drain, and I saw a cat running away, straight down and turned right into another drain leading into the corner house down my road.
She behaved in the same way this afternoon as well.
Assuming that it is Joanie, at least I know she is near.
I've consulted friends to ask for ideas on how I might be able to get her to come home. Putting food out won't help at all because my cats would instantly eat it all up. I don't know what else to do now.
We took Suki down the road again just now, but Joanie did not appear.
It is already getting dark now.
She's been in my house for more than 2 weeks now, and on the first five days, I was with her for many hours in the hospital. She knows her name and she knows me.
Poor Suki is sleeping against the router now, for warmth.
