What to do when a found cat's microchip is unregistered

When a pet microchip lookup returns as unregistered, rescuers cannot contact the owner directly through the registry database. This leaves them relying on alternative checks like neighborhood outreach, local rescue scanners, and requiring proof of ownership before handing the animal over.

  1. 1
    Putting up paper collars on the cat
  2. 2
    Calling the specific microchip registry company or the number on the AAHA site to find the administering vet clinic
  3. 3
    Posting in local lost and found pet groups on social media and Reddit
  4. 4
    Putting up physical posters around the neighborhood
  5. 5
    asking callers to describe the pet and its collar
  6. 6
    requesting photo galleries or metadata as proof of prior ownership
  7. 7
    asking for veterinarian or hospital records
  8. 8
    requiring contact info for the person who supposedly gifted the pet

“Well one of our neighbors does some rescuing (not affiliated with anyone) and she had a cat scanner but on the AAHA site the microchip number says "not registered"... Is there anything else we can do to find owner contact.”source ↗

“Ngl them having no photos of a kitten they had for two days is crazy. But trying not to judge them on that. Wait to see if anyone sends any photos or proof, if you dont get any do not give it to them.”source ↗
