I think it might be in the same category as Pothos, bad for pets to eat but ok to sit on, The Peace Lily (Spathiphyllum spp.). I have no experience with it though.

In addition to the plants Don mentioned, my American Green Treefrog loves the various Peperomia obtusifolia. Nice sized leaves for them and some grow upright to fill a vertical space.
