Take the cat to the vets and they will check the microchip and if the cat is registered the owner will be found

Tha't what i've done this morning, but they told me that the cat has an american microchip and that they coundn't find something about it. That's why i'm posting a thread to all glocals members.

Maybe give a call to Anis? Its a long shot but,,,,,

Did you try to see if the cat was registered as missing at SOS-Chats, SPA or elsewhere?  I have these links to hand as I found a kitten last week in Nyon:

Hello Michele, all is done, but in fact the poor cat is dead and i'll try to inform the owner of that. I'll put some flyers in my neighbourhood today.

Thanks for help.
