Animal Kinship VI is an incredible skill that allows you to nibble pigs without petting them first, and when you have this skill they are only too happy to let you nibble. Twice. Unfortunately, I think I have encountered a bug that occurs when you have AK VI and try to nibble a pig at home:
Repro Steps
-----------
Get AK 6
Capture a piggy and bring her home
Nibble her
Expected Behavior
-----------------
She lets you nibble her and gives you +3 meat
Actual Behavior
---------------
She complains that she's all 'nibbled out'. You feed her and proceed to nibble. Same message.
Pet her and now she's happy to let you nibble
I feel bad pointing this bug out as they give you +6 meat and all you have to do is pet her once. But I didn't spend days learning AK 6 for nothing so here is the bug report. :)
