If you have lost your cat, you can announce this via our platform.
First, make sure your pet has in fact been registered on CatID. It might have been registered via another channel. You can check via the Search function on the site, using your cat's ID number.
If so, you can ask your vet to input the notification via the online application. This online application also gives keepers access to the functionality that lets them send notification of their lost pet.
