They're just licking thankfully — bunny nibbles hurt!
As I said further up, the soppy part of it thinks it's because they love me. The rational part of me thinks it's because they like the taste of the salt on my skin. Maybe it's a combination of both, but one thing I do know whether they love me or not, is that they wouldn't get that up close and personal with me if they didn't trust me and feel safe with me, so that's as good as bunny love!
