It's pointless to microchip your pet…
Basically it cost €70-€80 to microchip your pet, thinking they going to help you if you lose it (because that's what they tell you as they philosophy), but in reality they only make you life harder (for 7 mounts at this stage). After my dog got stolen they told me that someone wants to change the ownership, but they refuse to tell me anything about her whereabouts, so microchipping is totally pointless.
