I have no idea, though Amy, my (rather large...) dwarf lop seems to be half daft, half smart. She has her ditzy moments where I don't even know which planet she's on, then she turns around and outwits me or does something I have no idea how. She often combines these attitudes, doing something clever that seems really stupid. Pipkin, my hand reared wildly, was quite smart with judging distances and angles and climbing up on things, and Baby, my very first rabbit and another dwarf lop, actually trained herself to go from my room, across the hall and through the kitchen to her hutch at the back of the house around bedtime.
