Free for Cats!
A generous cat lover has donated microchips to Marin Humane so we’re currently offering them for FREE for cats while supplies last! Bring your cat to the shelter during regular business hours and our Customer Service department can help you. Please note this offer is valid for Marin residents only, while supplies last. Please call 415.883.4621 for more information.


Marin Humane hosts an annual vaccination clinic every June. VIP Petcare holds weekly mobile vaccination clinics at local Pet Food Express stores. Some vet hospitals also hold their own vaccination clinics or you can contact your own veterinarian.
