Was my colleague’s follow-up channeling about seeing insulation being pulled out near his front door, but no mouse droppings, an accurate explanation, that those signs of a mouse being present for a time were created by you to provide room for doubt?

This, again, was an accurate channeling in all respects. In fact, the improbable nature of the answer is actually good evidence, if you think about this, that he is not somehow inventing an answer in some part of his mind, but truly getting information from beyond his own consciousness. This was, in fact, a divine clue as well, being shown openly under circumstances where someone with a highly developed intuitive ability and quite knowledgeable about how we work would get intrigued, and while perhaps troubled at the strange circumstances on display, was receiving a continued tutorial about what can happen with human-divine partnership.
