That's the current status, though we don't have a lot of potted
plants. They limit floor space. Hence the interest in something
they could walk on, even if it needs to be swapped out
periodically.

ok, then, have you tried full spectrum UVB bulbs. i'd think they
would help with depression in the patients, and i know that they
work pretty well on the plants in my tort pens. i mostly use the
CFL UVB bulbs, but you can get tubes as well.
i would try getting some heavy duty jelly roll type pans from a
kitchen supply (or plastic boot trays maybe?) and punching several
drainage holes. if you know a sheet metal worker, you could get
actual 3x3 pans made, but jelly roll pans might be as close as
commercially available. fill with a sterile medium (even damp paper
towels) & sprout rye/wheat grass. those both grow pretty quickly,
so you might be wanting to start new trays at least weekly, so you
can swap out the too tall or trampled grass.

i'm not much on squirrels, but i've repaired a few raccoon & birds,
and a big brown bat with a torn wing (hint: bats do not stay in
bird cages g). i'm more into reptile repair myself. it's amazing
what a turtle can survive.
