Wait, I have a guess about what's happening. Tell me if I'm wrong:
There are a couple conditions for camera tracking. One, the scenery has to have enough lighting to fully track. Two, there has to be a fair amount of stiff objects sitting around, at least enough to cover sufficient dots with (I may have been mistaken when I assumed that the software could track my cats movements).
If I experiment with these ideas, and if everything turns out all right, you may not need to look at the footage and data or whatever else. Thanks for the discussion.
