No, the vast majority of ferrets can be giving the implants without
sedation.  I give them a treat such as ferretone, ferret vite, nutical,
or laxatone.  While they are eating I give them the injection of the
implant before they realize what I am doing.  In young or hyperactive
ferrets, scruff them and hold the treat up to them as you give the
implant.
 
I have not taking any of the implants out, and I do not think that is
necessary unless there is actually a problem there.  So far no problem
with the "old" implants under the skin.
 
Hope that helps,
Jerry Murray, DVM
 
PS My 2 ferrets will be getting new implants this weekend.
