i let them all roam on there hanging plants. my cross kept going all the way dop the pothos vine and i was worried he'd get off and roam the house(it happened one time before, i wasn't paying attention, lol)so i tied one of the long vines to another pothos to give more "room". he loved it! back and forth up and down the vines finally settling in looking over the living room as far out as he could get.
