Do not wait a few days and see if the pet shows up first. Many an owner has come to the shelter only to find their pet went to a new home or worse.
Adoptions are final.
New adoptees of unclaimed strays will not be contacted to return a pet if the real owner shows up. As a general rule, once your pet has been missing overnight, please call the shelter as soon as possible. Go to the shelter and look at all the animals. It is not possible in many cases to confirm a pets identity over the phone because no two people describe an animal the same way. Be sure to tell a staff member the purpose of your visit because sick or injured animals may be at a vet clinic or in a different room not visible to the general public.
