We TNR on a regular basis and if we do not want a feral ear-tipped then we don't use the organizations that do this. Usually they have numerous ferals going in and out their clinics and to try and remember to not ear-tip is probably difficult. This is a universal method that all groups working with ferals agree upon. It's too bad this happened, but it's not terrible to have a tame that's ear-tipped. We have a couple now and we barely notice the eartip.
