I was watching my new garg earlier fail at trying to climb the screen on my laptop and then try eating my mouse cord, and an idea hit me. Cresties, gargs, and other rhacs are semi-arboreal to arboreal, so I figure that if, say, a closet wasn't needed, perhaps adding the necessary foliage, food stations, and such, would free roaming similarly sized rhacs (say cresties and gargs mainly), wouldn't a free roaming group be possible?

Just a random idea.
