as far as I understand it, anti pill fleece has the tightest threads, so it is
most difficult for them to get stuck.
we cut nails about 1 once per month. but probably could do it every two weeks
to keep them from getting stuck. their nails seem to get sharp after about 2 weeks.
or some use a coconut as a sleeping area.
so that is the best I got, cut those nails.
I been thinking of getting a file, and while I sit with them try to file the
sharp tips down some, see if this helps with getting stuck in between cuts.
