Ooh I'm not sure if there is, I'll have to take another look.
It was basically things like yes, size is needed, and security is needed. But your bunnies don't understand padlocks, so while you may know they're secure, they don't know that, and want places to hide with more than one exit, places it jump up on, places to peer out from, that sort of thing. A large open space to a bunny doesn't mean 'Ooh look at all that nice empty space for me to run in' it means vulnerability and nowhere to hide. So it was very much turning our perceptions on their head and thinking about what we do translates into bunny language.
So in this context I guess sharing ideas and good practice, and showing our accommodation for others to suggest ideas for bunny-language'ing it.
