My 2 have South African fitted American-manufactured microchips just to make it even more fun. They are all read by the EU scanners luckily though. The vet in France read them with no trouble and they were registered on the national felin register as 'foreign'
Here in England the vet entered their chip nos in his computer and Petlog had no probs at all with the foreign chip either. Miss Boopy's chip will be fine with Petlog. It will probably have numbers and FR on it?
The only trouble I had was that Swampy's has a 0 in it, which caused all manner of hysterics as no-one knew if it was a 0 (zero) or a capital 'o'. Some scanners read with a line through it and others don't. I had to have all his antibody titre test paper work redone by the Toulouse lab as the first time they put the letter O. They did it with much gallic muttering about les anglais fou (mad english)!
Are Petlog good? In France, Miss B was probably on the wonderfully named "Fichier National d'Identification des Carnivores Domestiques Autres Que Les Chiens" = national ID folder of domestic carnivores other than dogs!
Which reminds me, haven't told the good dames of Paris that I've moved. I would love to hear you ring up that lot and give her name as 'Miss Boopy' btw
Just to add another anecdote: the SA guy who imports and sells the chips out there has put 4 (so he told me) in his own leg to check if they move or which scanners can read them....ho hum
