All good advice.
We hang beach towels around the pen to give our mom some privacy and cut down on any drafts if it is cold.
Be sure to give the calcium as Barb said. 1/2 tablet a.m. and p.m. I crush mine up and mix it with a little cottage cheese. My moms love it. I also think it has a little calming effect -- just like calcium does on us.
Good luck.
