Thanks for your reply. If I buy he spray or other deterrent how will affect my own cats?
Thanks again. I understand that there is not a lot that can be done except to frighten the cat away. My concern is that the cat belongs to someone and perhaps is lost. We do not have animal control as such but I could take it to the RSPCA tomorrow although I am working until late.
Meanwhile my cats are asking to go out - they do not use a littler tray. Perhaps I should not have bothered you but thanks anyway.
Really sorry but I have to go out. Many thanks
