Our rabbit won't place "chase" but she will play what I've come to call Toreador! It started with my big floppy bathrobe, but now any garment will do - I hold it so it's bottom is near the floor and shake it a little, and she will charge it, like a bull - she even makes a little grunting sound every time, and charges through/under it as fast as she can! She taught me the game when I was hanging up my robe in the morning, now we play almost every day!
