I was fortunate enough to receive a box of bunnies from Carol, and took one out this evening. It was extremely amusing, but I was surprised that it didn't hop behind me - in other words as I entered and exited an area, the bunny was not marked in chat. I believe that pets usually do enter and exit behind their owner.
I know this is not exactly a game-threatening problem so I wasn't even sure whether to post or not. But I just thought I would let you know in case it was significant in any way (*knows nothing about coding, et cetera*)
