Obviously, the cat was not happy with the prospect of leaving its territory. That's why nobody could find it when the Minskikhs were to move from their old home. However, when the cat realised the masters had really gone, its love for them prevailed and the cat set off for a long journey. Now, the right question to be answerred is how the cat could knew which direction its masters have gone to? In my opinion this is just a prime example of a phenomenon that living beings are generally capable of having a long-distant communication that is not based either on acoustics, or on visually seing each other. That is what is usually termed as "paranormal" way of communication, but I am of opinion that it is in no way a "para" kind of activity. It is just "normal" phenomenon, though not quite usual among humans for it has not been investigated fully. The whole story is wonderful. Hope the Minskikhs will be happy together with their dear friend (family member).
