UK Microchipping

[Millys Mum]

Chips can migrate, Tazs is off course down his shoulder but thats where i found it from day one 

Get it scanned each time you go so you can keep an eye on where its going.

I know when I took 'jimi-the not so stray anymore' in to the vet to look for a chip she went all over him looking for one just to be sure, she virtually went down his tail  so clearly they do move about quite a bit...

He goes back for his boosters on the 16th so I'll get the vet to scan where I think it is.

shadow's was inserted between his shoulder blades and is now several inches down his arm ... They are not supposed to migrate, but they do.

I was petting Gizmo this morning and I swear I felt the microchip on his right side about two inches from where the vet put it.

Now I wasn't there when Lirael & Smoke were chipped but I was for Giz, is it normal for them to do about an inch below the shoulder blades?

I always thought it was between the shoulders, but that is from watching the vets in the US.

They also did all the injections in the same area which caused 2 of my cats to scream/hiss. I know things are done differently between countries but I wasn't sure about placements of the microchips.

I know my one vet in the US used an ear thermometer instead of the old in the bum one which shocked me in the UK... the poor kitties.

Anyway, should I worry about the chip moving or is this a normal thing?
