Where can I get the pet chip for my cat?

If your pet still does not have a chip, you should get in contact with your veterinarian. Basically petWALK pet doors support all FDX-B -based pet chips according to ISO standard DIN / ISO 11784 / 11785. If you have the choice, we recommend transponder branded DATAMARS (in Germany and Austria sold by Virbac veterinary medicinal products under the trademark BACKHOME by veterinarians), as they identify the best read range.
