for me one thing comes to mind.
we went to very nice vet hospital, paid $100 ( I think for each glider to have
a checkup after we got them.) They tried to cut nails but couldn't do it, and
they seems only somewhat experienced.
we later went to a small older vet hospital, paid $40 to have 4 gliders checked
and $40 for a fecal test. a father and son vet both with glider experience and
they seemed to know a lot.
so the smaller less fancy place was better experienced and cheaper.
so maybe check around the area.
we have an emergency 24 hour vet 2 miles away, but they have NO glider experience
