You know the angles of both cats, and their relative positions (ie the angles A and C, and distance between them, b), then you can figure out the position B).
You’re using three inputs, only only one of them was merely implied. But the person sitting there can see where the cats are, and thus knows their relative distance.
If cat A was (from the POV of the human) in an unfixed position, like having 30 virtual duplicates around him, or be in a magic mirror house or something, still visible at what direction he’s looking at, but not where he is, then the sitter couldn’t know just from the position of one cat and the angle of both cats stares.
Yeah.

See?
Triangulation
Does the prospect of 2 cats staring at a point not immediately invoke the image of a triangle for most people?
