I would like a way to remove family relationships between cats, seeing as coming up in the development plan there's going to be a way to add them but not remove them. We can remove friendship relations, so why not family relations?
I imagine it working like this:
I apply family removal item to Cat A. Cat A no longer has any family in their list, but if you go to any cats that Cat A was family with before, Cat A still appears in their list (Applies one way only). Alternatively it can apply both ways, but then that starts to affect other peoples cats and I don't think that good.
I can see problems with trying to use this item on cats with beans, so perhaps it can only be applied to cats that don't have any beans/expecting beans?
Edit: I don't think this poses a problem for determining if a cat is a Nestor cat or not, since the origin tags are different for Nestor cats, Business card cats, and if a cat was born to your village. However, to prevent confusion, a marker that an the item has been used or changing the above to a hiding option instead of a removal would also work as well.
