Got to be optimistic though.
Cats do tend to have a mind of their own though, much more intelligent than dogs. Given the chance they will stay where they want to be.
Know this from experience from one cat.. continually brought him back after we moved. Insisted on crossing a main road to be where he was originally. don't know how he knew the way, coz he was taken away in a basket. In the end stayed with the ex neighbour. He was happy there. probably missed his mates! So be it.
