Lost Senior Tabby Cat in Thorold – Help!

My indoor ,15 year old male cat went missing Thursday June 27th from Vanilla trail in Thorold - Calderwood. We believe he jumped off our 2 story deck as sometimes he I likes to sit under my potted tropicals and we may have overlooked him. He may have also slipped out the front door in search of grass ! He’s neutered and has no front claws. He is timid and will certainly be frightened and reluctant to anyone he doesn’t know. His coat is a beautiful mixture of grey, black , brown and cream . He’s considered a tabby. He’s also overweight and has an adorable belly .
