Have to try it
I like to speek to them on a low soft voice and say sweet silly things asking how was its day and stuff like that and they seem to like it too because they listen.

Just now, Fister was standing in window sill looking out in darkness - all quiet out there. I came up and put my hand around his chest so he didn't get too cold and whispered to him - asking if was seeing any other cats out there etc. It was really funny to see how his ears were sticking up, listening!
A such a tender picture !!! I wish I could stand behind the door looking at the scene
I'm pretty sure that the word CAT alerted him.
Ahh,Fister, never tired of you ....
