Artica is chipped but not sure what the brand is. She was chipped at 8 weeks old and each time we go to the vet her chip is checked. It hasn't moved as of yet and there has never been a problem reading it.

If you want to travel outside of your country here and still within the EU or outside the EU it is mandatory to have your pet be it dog or cat microchipped. They also have a pet passport for travel within Europe. Vixen & Phoenix are both microchipped as well and when the other 3 kits go in for their annuals they will be getting theirs done. The vet felt they were too small to be microchipped when I had them in before.
