If you have a Facebook, Twitter, Instagram, or other social media account, post information and a current photo of your missing pet to friends and followers. Ask them to spread the word and help further the search.
Search your home
Cats and smaller pets (like ferrets and rabbits)
are especially prone to going missing in the home.
Tip: Try also leaving food or treats out for them to find
Search your neighborhood
Searching the area in the immediate vicinity of where you last saw your pet is very important. Go slow and pay close attention to areas that may offer sheltering (Like bridges, ravines, picnic tables, etc.). Be sure to ask any pedestrians you see if they recently saw your pet and leave your contact information or a lost pet poster with them.
Go back to the last spot you saw them
It may seem like a long shot, but go back to where you last saw your pet and leave an article of clothing (preferably something that you've worn for at least a day) and go back and check this spot often.
Check in with all of the places you have contacted to see if they have heard anything or have any updates.
