Are there good techniques for this, other than offering him treats whenever you vacuum to develop positive reinforcement? The first time I vacuumed, Moby bolted and flung himself into the side of my mattress, like he was running in blind panic. It was bizarre and made me feel terrible. But I allow him free range in my room, which I have bunny proofed, so I will have to vacuum somewhat frequently. Whats the best way to help his fear of it?
