It grieves me to have to tell you that as far as I can be certain Leo is dead and gone.
I duly phoned the Council yesterday morning and they confirmed it was a black&white cat that was removed but they also immediately incinerated his body. I understand their responsibility to do that quickly but I am angered they did not scan him for the record. I was told they do not have the time or the equipment to do so. I will write to the South Lanarkshire Council's Director of Land Services to express my dismay that they cannot make the time or have the small hand-held piece of equipment to scan what was obviously a family pet as a matter of standard proceedure. It may be a nuisance to them but it is of great importance to me and others who might lose their furry friend and not know what happened.
I still look for him at the window.
