The advice you gave covered all bases. What was particularly effective was doing the 2am walk with heated up sardines. I also took his blanket with Coco's scent on it. I also included checking of drains with torch. I walked around streets close by and when I arrived home I left his kitty litter and sardines in the yard. leaving his blanket over the railing on balcony. Within 10 minutes he came crying loudly into the yard. Hungry as a lion! I was so shocked because after 4 and half days of looking and no sign he came home! Thank you so much for all your help and support. Much appreciated and will definitely recommend others to register their lost pets with your organisation.
