I've only been bonding Gizmo and Nova for about a week now, and things are going great. I've seen grooming (both rabbits), mounting, mirroring, laying near each other, flopping, eating in front of each other, etc. No aggression whatsoever from either rabbit. How do I know when the rabbits are ready to 'move in together'? I don't think we're quite there yet, but I'm not sure when I'll know, or what I should be looking for?
