The rabbit has been dropped off and the address discarded, as requested; take good care of Sandwich, I've become a bit fond of him.

It's hard to tell - I'm not sure if It wasn't interested in him or if the rabbit remained well-hidden. Either way, It did not try to eat him - there was no more bruising than usual from the chains, and I think It certainly would have been aware of the rabbit's presence - usually It seems to react violently to any increased nearby human activity, so.
