Yes stick to just greens for now, I would also leave out any of the dried foods until you notice the greens being devoured on a regular basis. Also, Uro's are much faster then you think, if you take it outside, say goodbye. Only by providing a HUGE escape proof and predator proof enclosure is going to work outside... probably not too ideal for most people. and DEFINITELY DO NOT put the Uro on one of those lizard leaches!
