It's simple: figure out its head so you can get through its head.
The generalization maintains that round face cats are low-key, quiet, shy and submissive, while cats with triangular heads are curious, vocal and active. Cats with square heads are seen as affectionate and keen to please their owners.
Arden Moore, author of 'Fit Cat: Tips & Tricks to Give Your Pet a Longer, Healthier, Happier Life' made these assertions based on her personal experience with cats. Despite lack of scientific proof, Moore's “theory” strongly advocates the connection between looks and personality in cats, based on her observations that “different breeds of cats, with distinct behaviors, often have the same face shape.”
But before Moore, Kit Jenkins, Program Manager for Petsmart, also came up with this interesting theory in 2009 based on her 20 years of studies on the behavior of cats and dogs at the animal shelters. Her “Theory of Cat Face Geometry” laid down three distinctive shapes for cat faces: square, round, and triangle.
Do you think Jenkins' and Moore's observations apply to your own cat? If your cat shakes its head, then maybe not.
