Lost Pet Poster.
Years ago in my home town, if a pet went missing, you could assume it would end up on the menu of the local restaurant. I stopped going there when the meals contained more fur than meat.
If you also have lost a pet that is dear to you, you can use MS Paint to create an effective poster to distribute to the local area to get some response. It is good to try and get an accurate likeness of the pet and offer some description of the animal to encourage locals to look for him or her.
