Well, it's quite easy, technically. The vet will know exactly where the chip is if it's migrated by scanning for it. However this will require the ferret to be completely under. I have several fuzzies with melatonin implant "husks" (the empty plastic case) still under their skin and the vet forgot to remove it during an adrenal surgery for one. Great, y'know? But another got her tooth fixed (actually removed) and THAT vet forgot too, but went back and did it later for free for me. Isn't it funny how they can forget the little extras you ask of them? LOL!
