I see favorite cats on my walks too.

The old Calico who hangs around the top of a particular hill.
(All of Sheffield in built on 7 hills like Rome. Hence I spent most of my days walking up and down hills.)

A beautiful Tuxedo kittie who calls to me and as his garden starts at 6 foot mark. He is lying at head level in his flowerbed. I do talk to him, he is very vocal.

And too many others to mention.
