I'm working on the finishing touches of my Redguard style Stable with an enclosed Pen (pictured below). I've created random path nodes for each of them, and made some of them Sprinted so that occasionally it looks like they're pouncing on the node. Works pretty well actually. And I've set up the timers so that there's rarely more thann 2 of them wandering out of the stable at any given time.

But then I recalled how another game has interactable toys for your pets. And the I realized, I'd absolutely LOVE IT if I could toss in a balll furnishing that can be collided with, and it'd bounce/roll accordingly so that it'd look like my kitties were playing with their favorite toy.

Please note that the pen isn't to keep them in. It's to keep people out. =D
