One of the first things you should do is get the animal scanned for a microchip. This is usually the quickest way to reunite found pets.
Second, list them with your local shelter, on Nextdoor, PawBoost, and in various lost pet groups on FaceBook. Be sure that anyone who claims the lost pet shows some form of ownership.
Shelter2Rescue is not able to accept stray animals. We are a volunteer and foster-based organization with limited resources.
