Surprisingly, our feline crew have orderly minds.

Granted, cats generally have a strong preference for tradition and regular routines, but ours even carry it over into their sleeping arrangements.

Right triangles are popular.

Though equilateral triangles are almost as common.

And the straight line is evergreen.

(The line is straighter than it appears in this photo. Kokoro and Rhubarb were lying on my legs, preventing me from aligning the camera properly.)

Having said all that, I should clarify that such geometric specificity applies only at the interfeline level. Individual cats are always free to be as goofy as they wish in their pursuit of teh kyoot.

And they do.  Take a closer look at Watanuki in that last photo:

Note the paw over the nose, the brilliantly pink toe beans, and, most important of all, the tail carefully curled around the end of the rear leg.
