How do they know? Just as they spurn cheap vegetables and love premium leaves, they can somehow tell that this Busybunny mini maze is of high quality. To us humans, a cardboard box is a cardboard box. I gave the rabbits many boxes, but they just like this one better! These two rabbits have such expensive taste!
See? Blackie loves BusyBunny too :P He has spent long hours ripping, chewing, digging and generally being busy, and has left my doors alone. Hm...it looks like they need a new mini maze soon :P
Just a thought...don't you think Blackie looks so handsome here?
