If your pet is missing visit all area shelters often.
Search your home- keep in mind that pets can just get scared or nervous and hide. Don't rule out the possibility that your family pet is (literally) in your own back yard. Check all areas that are accessible to your pet- inside appliances, under furniture and in drawers and closets. These are favorite hiding places for cats.
Ask your neighbors- talk to your neighbors! It is possible your missing pet may be trapped in their shed or garage without their knowledge. If you have recently moved check in with your old neighbors, many pets try to get back to their old homes.
post an ad on Craigslist in the Lost/Found and Pets sections
post a Lost/Found ad in the newspaper- it's free in the Spokesman Review!
post flyers in the area your pet went missing
If you have found a pet with no ID, take it to a veterinarian or shelter and have it scanned for a microchip.
If you have lost a pet, don't give up! Many pets are not taken to shelters until they have been missing for several weeks. Please keep looking, and keep checking all area shelters- your pet may be waiting for you to find them!
