we use the 2 person method. its on video on youtube, how to cut a crabby glider
nails. One person holds glider tight holds out nails, second person cuts.
AND we have never had a glider hate us for cutting their nail, some of them dont like it but afterwards when they are not hurt they run back to pouch but it has NEVER seems to cause long term negative problems, in fact it almost seems like that fact they get away unhurt makes it ok with them.
