I've just adopted two cats who, though adults, apparently like to try out my plants. I'm looking to replace some of my toxic indoor ones (monsteras, pothos, snake, dracaena) with safe plants. 

I'm looking for cuttings or plants of any of: boston fern, peperomia, spider, haworthia, bromeliad, polka dot plant, maranta, friendship plant, echeveria, or money tree. 

If you have any cuttings of any of these, I'd be grateful. I can also exchange some of my mature toxic plants for mature cat-safe plants, if interested.
